It achieved the following turning point with Angular 5's landing on November 1, 2017. I don't know about you however we're extremely energized that it's at last here!

  • JSON is an expected default and never again should be unequivocally parsed.
  • Permanent ask for/reaction objects.
  • Advance occasions for both request upload and response download.

#2 Multiple names support for components and directives

In Angular 5, you would now be able to give numerous names to your components and directories while exporting. Sending out a part with various names can enable your clients to move without breaking changes.

#3 Internationalized date, number and currency

Angular 5 has new pipes for date, number and currency for better internationalization bolster crosswise over browsers, evacuating the requirement for relating polyfills. The pipes depend on the CLDR to give broad local support and configurations for any areas you need to help.

#4 Build optimization

The Angular group concentrated on making Angular 5 quicker, littler and less demanding to utilize. In Angular 5, generation fabricates made with the Angular CLI will now apply the assemble analyzer as a matter of course. The build analyzer expels Angular decorators from your application's runtime codes subsequently diminishing the span of your package and expanding the boot speed of your application. Furthermore, the build optimizer expels some portion of your application that isn't required amid runtime by means of tree-shaking. This activity prompts a diminished package measure, and speedier application speed.

#5 Faster compiler

The Angular compiler bolsters incremental forms, figuring out how to decrease the manufacture time by 90% in tests on genuine tasks by utilizing Typescript transforms. Since the arrangement time has diminished under 2 seconds for substantial activities, AOT will be turned on as a matter of course in a future rendition of the CLI.

Google is giving guidance on the most proficient method to move to Angular 5 from previous versions.
