Angular 12 is an exciting new release of the popular Angular framework. It brings with it many of the features that developers have been asking for, including improved build times, better debugging capabilities, a new in-browser stack trace, and updated framework-wide innovations. Here are some highlights of what's new in Angular 12.

Improved Build Times

Angular 12 has improved build times due to upgrades to the Optimization pipeline. The new Rollup-based bundler can produce Tree-Shaken JavaScript bundles that are much smaller and faster, resulting in significantly reduced build times. This also reduces the application's overall memory usage.

Better Debugging Capabilities

Angular 12 has improved debugging capabilities by introducing the new in-browser stack trace tool. This helps developers debug their applications more quickly and efficiently, by allowing them to explore the call stack, view variables, and even set breakpoints.

Improved TypeScript Support

Angular 12 has enhanced TypeScript support by introducing the new TypeScript-aware template type-checking system. This helps reduce errors by early-detecting type and template related issues. The new system also allows developers to make use of type-safe templates without any extra configuration.

Support for Differential Loading

Angular 12 now supports differential loading, which is a technique that enables different versions of a script to be loaded for different browsers. This means modern browsers can load a more optimized version of JavaScript while older browsers still get backward compatibility. This can significantly improve performance and reduce the size of scripts.

Conclusion

Angular 12 brings with it a host of innovations and features that makes it easier and more efficient for developers to build powerful web applications. From improved build times to better debugging capabilities, the new version is sure to make developers lives much easier. So if you’re looking to develop with Angular 12, be sure to take advantage of all its new features!
