Difference Between Angular 4 and Angular 5, Compare Between Angular 4 and Angular 5, What is new in Angular 5 over Angular 4

Introduction

In the previous write-ups we have seen that how the JS frameworks React, Vue and angular differ from each other. The present one focuses on Difference Between Angular 4 and Angular 5. As per the promises made by Google, developments have been taking place in the Angular framework and are released two times a year. The ultimate goal is to make the framework as user-friendly and effective as possible.
Differences Between Angular 4 and Angular 5

Angular 4: What was there?

Before proceeding to the differences, it would be good to know what actually happened with Angular 4 framework.

  • The release of Angular 4 was a sudden jump from version 2. It has brought in a lot of new features. The biggest achievement that this version has done is to make the framework smaller and faster. This means it is light in weight.
  • TypeScript 2.4 was introduced which would act as JS superset. Interfaces and classes are some examples where it could be applied hassle freely.
  • The framework is no more clogged by the presence of Animation package integrated onto it. The 4 has segregated and separated this package from the core package.
  • Web developers could code much faster than before, by using the ngComponentOutlet, thus paving the way for the use of dynamical declaration methodology.
  • Universality is an impressive feature that version 4 provides. You could simply render the application outside the browser.
  • Prior to Angular 4, pattern option was the only way to validate an email input, whereas now, there is an inbuilt validator to take care of it.

Angular 5: What is there?

  • Compilation process has been improved by many times in the Angular 5 version. The framework in 5.0 does it in an incremental compilation which would help to rebuild the application more quickly.
  • Build Optimizer was the tool that got introduced with this version and actually does the job of reducing the user's bundle sizes. This would let the application to boot in a very short span.
  • A quick reconstruction in an incremental manner could be done unto Typescript with the powerful transformation tools that Angular 5 provides.
  • There is no more the need to use the @angular/HTTP library as the HttpClient is now much widely accepted and appreciated.
  • Developers using the Angular 5 can now track down the entire life cycle of the router including the start of running guards and activation completion.

So what is it different?

When we Compare Between Angular 4 and Angular 5, there are few but important notable differences. The first one is that the loading time is relatively much lesser in the case of 5 and the application executes much faster as well. Angular 5 provides support for AppShell, the tool that helps to render the application with the use of a router. The mechanism of identifying errors in the decoration of templates have been improved by a large scale. It clearly explains the source of error. Thus, on a whole, angular 5 has few bugs of its predecessor fixed and the services have been scaled to an extent where the user would find it much more easier to work with the Angular framework.
