The 3 key benefits of Angular 2

We've got 3 key benefits to using Angular 2!  #angular2 #angularjs #typescript

  • Angular 2 has immediate performance gains over Angular 1, the approach to DOM manipulation and rendering allows Angular 2 applications to run smoothly on a wider range of devices.
  • TypeScript is statically typed, allowing for the TypeScript compiler to catch errors on compilation that would only be caught during runtime in JavaScript
  • While code quality can sometimes be an afterthought we all know how import a clean code base is when developing large/complex apps.
  • TypeScript is updated independent of the browsers, this allows you to constantly be using new features of the language without having to depend on browser updates
  • The convention over configuration nature of Angular 2 apps makes it easier to build large applications with a consistent and easy to learn structure.

After working with Angular 1, and now Angular 2 on a number of projects we’ve discovered some key benefits of using Angular 2 as our go-to JavaScript framework.

A few things we’ve learned from working with Angular 1 & 2

After working with Angular 1, and now Angular 2 on a number of projects we’ve discovered some key benefits of using Angular 2 as our go-to JavaScript framework.

Angular 2 recommends using TypeScript as the default language, and doing so offers a number of benefits over JavaScript:

TypeScript has fantastic integration with some editors (we use VS Code), which allows for code completion, error handling, and great refactoring tools: Jump to/peek at definitions, find all references, renaming symbols, changing all symbol references

Angular 2 also allows for more consistent code quality between developers:

While code quality can sometimes be an afterthought we all know how import a clean code base is when developing large/complex apps.

Angular 2 has immediate performance gains over Angular 1, the approach to DOM manipulation and rendering allows Angular 2 applications to run smoothly on a wider range of devices.

Angular 2 also has additional methods to get further increased performance if required:

Angular 2 has a much smaller memory footprint, this was an issue with Angular 1 and something the team focused on improving. Angular 2 has a memory footprint roughly 60% of the size of an equivalent Angular 1 app.

The garbage collection process in Angular 2 is vastly improved, this allows for for higher frame rates and less dropped frames in animations.

These performance gains are exceptionally noticeable on mobile devices, which generally have lower processing power (vs. tablets, laptops, or desktops).

The performance gains Angular 2 has over Angular 1 makes it possible to build innovative UI’s.

The convention over configuration nature of Angular 2 apps makes it easier to build large applications with a consistent and easy to learn structure. This allows teams to onboard new developers with relative ease.

Angular 2 faces adoption issues, it’s not as easy to hack things together as it was in Angular 1 and other smaller libraries like React have filled that gap for many people.

Angular 2 is more niche focused than Angular 1 was. It’s going to be better for building large scale apps, those that you’d see at companies like banks, or the government, but less suited for the smaller apps Angular 1 was used for.

If your goal is a small side project then many of the benefits Angular 2 bring to the table will likely not apply to you, and it may be significantly slower to develop with than other options that are available. If you are looking at different options to update enterprise grade software with, project Angular 2 will bring a lot of conventions and best practices to your project that will help with consistency, reduce code reuse and structure.
