使用JavaScript或TypeScript的Angular 2.0？

Question

Which is the recommended way to develop angular 2.0 application. is it with javascript or typescript. i found difficult to start the angular 2.0 with typescript which is entirely different from the javascript.

Answer 1

In fact, TypeScript is a superset of ES6. In short, you will have the following in addition:

• Type checking (class properties, method parameters)
• Decorators
• Interfaces

Perhaps the gap between ES5 and ES6 / TypeScript is important but there are really advantages to use it:

• The compilation phase allows you to detect potential problems in your case
• TypeScript provides contracts (.d.ts files) of the elements / third-party libraries you use
• Support of IDE for completion

That said, you are free to use either ES5, ES6 or TypeScript. It's up to you ;-)

Answer 2

I think the decision must depend on the knowledge and experience of your team so that you can make a close time estimation of your project and avoid unwanted issue that might occur in lack of knowledge and experience. Hope my suggestion will help you to decide. Thanks.
