Have you been a strict adherent of Angular, keeping a tab on every single update and version?
So, you are in the right place, as the article will acquaint you with the latest release of Angular i.e. Angular 10 as well as its top highlights. According to the survey conducted by Statista, JavaScript with 68% of votes, is the most popular programming language among the developers, and Angular, being one of the most strong variants of JavaScript, is gaining immense popularity as well. The reason behind such popularity is the advantages offered by Angular that are Cross-Platform Development, impeccable speed and performance, amazing tooling, and a humongous community.
Angular helps to create an intuitive as well as dynamic SPAs (Single Page Application), using Typescript along with the HTML/CSS to code the Application which is compiled to JavaScript. Not only this, Angular comes with some of the unique features, making it stand out among other JavaScript Frameworks, such as:
Dependency Injection(DI)
Angular comes with its own DI, providing the declared dependencies, that are the objects and services from the external sources, at the time of class instantiation and making the application flexible, efficient, testable, robust, and maintainable.
Directives
Angular facilitates the programmer with a modular programming approach through the element called Directives, making the code more structured and clean. A Directive is a reusable component that embodies the functional and behavioural properties of a component, allowing to keep a record of the changes in an HTML code at one place rather than tracking it throughout the script.
Typescript
Angular uses a more advanced form of JavaScript – TypeScript, also called Superset of JavaScript. Though the language is a bit complex than JavaScipt, it promises higher security, speed, and better performance offered through early detection of errors.
POJO
Despite being based on a new language i.e. Typescript, Angular does not force you to create any sort of additional getters or setters, rather empowers you to manipulate the Object functionalities and properties as per the requirement through the same JavaScript code. The reason behind such a facility is that the objects used in Angular are Plain Old JavaScript Object (POJO) rather than the typescript ones.
Angular is continuously evolving and with its every version, it upgrades itself with some novel and tremendous features. Let’s check out the latest features that are included in Angular 10.
Upcoming features of Angular 10
Angular has come a long way since its release in 2009, releasing numerous successful versions ranging from Angular JS to Angular 9. Its latest version Angular 10, is already on the way to get released, in fact, two of its beta version already released in April 2020, which can be downloaded from GitHub. Angular 10 is expected to be smaller than that of the previous Angular versions, including some new features along with the pre-existing features of Angular 9.
Improved Performance
The Performance of the Angular 10 is definitely the highlight of this version, thanks to modifications like cache at the entry point manifest as well as the reduced size of the manifest, the performance of Angular 10 has exceeded its previous versions.
Angular 10 facilitates the caching of the dependencies (Objects and services) at the entry point itself, making it easy to access and reducing the computation load as well as liberating from the process of loading and computing the dependencies every time when required.
URL Matcher returns NULL
Angular 10 has updated the URL Matcher feature, which matches the routes against the URL. Unlike previous versions, in Angular 10, the URL matcher is allowed to return NULL.

Dependency Information should be added to Metadata
According to this feature, the declaration of the class should contain information about Angular decorators used in Constructors, if used, else the value should be set to null type. The Metadata should also include the ng-content selectors which are quite helpful for tooling. These tools extract the necessary information from metadata.json manifest file and offer suggestions for directives or components that are defined in libraries.

Decorated Derived Classes of Undecorated Class Migration
Earlier in the previous version of Angular, among the Base Class and Derived Class, Directives were added only to the Base Class during the Migration, which has been addressed in Angular 10. In this version, the missing logic has been added, hence, during the Class Migration, Directives are added to both Base Class as well as Derived Class, enabling the Angular Compiler to add Directive definition to the components of the Derived class.

Changed Service Worker(SW) Strategy
In order to address the challenge of registration of the service workers during the long-running task or timeouts, Angular 10 has changed the Service Worker Strategy, trying to wait for the stabilization of the Application, failing which registration automatically occurs after 30 seconds.

Avoid Runtime Error due to the Import of Non-Existent Symbol
This is a problem faced when a project tries to import a non-existent identifier, leading to Runtime Error, and hence Migration Fail. The reason behind this is the failure of TypeScript to compute the path from the original source to the imported source which is expected to provide the non-existent identifier. The problem has been resolved in the latest version that is Angular 10.

Angular helps to build both intuitive and dynamic SPAs, using Typescript and HTML / CSS to code the JavaScript-compiled framework.
According to Statista’s report, JavaScript is the most common programming language among developers with 68% of votes, and Angular, being one of JavaScript ‘s main variants, it is also gaining immense popularity.
Angular version 10, released June 24th, 2020 but this time with the beta edition. This may mean we are nearing the final release of the newest iteration of the typescript-based system developed by Google.
Nonetheless, this current angular edition will concentrate mainly on the environment and quality tools rather than adding new functionality. That may mean we will be seeing a lot of deprecation and updates.
Let’s take a look at the key features and value offerings for Angular 10!
This release focuses more on problem-solving. 700 problems were resolved in the process, and more than 2,000 were hit.
For a couple of years, the Angular team has been working hard on the Ivy engine and after Ivy was launched with Angular 9, the team is now able to concentrate more on problems that couldn’t be taken care of before.
Below are the latest features included in version Angular 10:-
Warnings about CommonJS import
Originally designed for server-side modules, CommonJS was not intended to reduce the production package size. Using dependencies bundled with CommonJS will lead to bigger bundles of code and slower applications.
Angular version 10 now alerts you when a CommonJS module pulls into your build.
Optional Stricter Settings
Angular version 10 provides a more rigorous project set up to build a new ng-new workspace.
ng new –strict
If this flag is activated, it initializes the new project with a few new settings that improve maintainability, help to find bugs well ahead of time, and allow the CLI to perform advanced optimizations on your application. Configuring the device as side-effect free to allow this flag to ensure more advanced tree-shaking.
New Date Range Picker
Angular 10 came with the all-new picker date set. You can use elements of both mat date picker range and mat date input range to use it.
Boost in ngcc Performance
For this angular 10 feature, an A Program-based entry-point finder has been introduced which is configured to process only entry points that can only be reached via a program defined by a tsconfig.json file.
Through using this method, one can catalyze the process in places where a number of dependencies are installed with relatively limited numbers of entry points which are actually imported into the application.
Async Locking Timeout
The design of Async locking timeout is also possible and could include assistance in the ngcc.config.js file, modification of the delays in retry, and retry attempts in the AsyncLocker.
Removals and Corrections
The key team of Angular developers conducted a lot of deprecation and removed some of the stuff from this website. Additionally, some older browsers such as Internet Explorer Web, Internet Explorer 9, 10 were also taken out of support.
Compiler Update
In the most recent Angular 10 a compiler interface was introduced to cover the real ngtsc compiler. Angular 10 also provided name spans for calls by process and property reads. In addition to this, the metadata also included ng-content selectors, Dependence data, and Angular language support.
It also accepts the procreation of the exact cost duration in the ExpressionBinding to ParsedProperty of a micro syntax expression which, as a result, may procreate the time to the ASTs template (both Ivy and VE).
TSLint v6, TSLib 2.9, and Typescript 3.9
Angular 10 supports Typescript 3.9. In JavaScript, typescript language is created by providing syntax for annotations and type declarations used by the Typescript compiler to type-check the code of developers. It cleans readable JavaScript which runs on multiple runtimes. With its great editing efficiency, Typescript helps save files through editors. Typescript 3.9 assists the team in their work on consistency, polish, and efficiency.
Generic with Module With Providers
The use of generic keywords has become mandatory with the ModulWithProviders in Angular 10. This was added to make the ModuleWithProviders patterns work with the rendering sequence and Ivy compilation.
Bug Fixes
Most bug fixes are performed in Angular 10, which includes eliminating unaddressed examples of the range in the parser, and the errors created due to migration when the symbol does not exist. In addition, the Terser Inlining Bug was fixed in Angular 10, too.
Combining with Many Transition Files
For Angular 10 new features launching, developers can combine several files in just one go. In addition, this file transaction is done through messaging functions.
Conclusion
Technology is continually changing and becoming up-to-date, making it important to keep track of the developments and adapt accordingly. For a while now, using Angular, the power of the Framework is no longer obscure.
With incredible features such as reuse of web elements, data linking, innovative tooling, and unwavering support from tech mammoths like Google, Angular has revolutionized the whole idea of web design and web development.
