What is the best ECMAScript version for TypeScript compilation?

As I delve into Angular2 tutorials, each section provides valuable insights. However, my progress came to a halt when I encountered the tsconfig.json file and noticed the line: "target": "es5". This setting indicates that I am compiling to ECMAScript 5.

{    
   "compilerOptions": {    
     "target": "es5",
     "module": "commonjs",
     "moduleResolution": "node",
     "sourceMap": true,
     "emitDecoratorMetadata": true,
     "experimentalDecorators": true,
     "removeComments": false,
     "noImplicitAny": false
   } 
 }

At present, I am utilizing ES5. The question arises - should I modify the target to "es6" or "es7"? What advantages come with using the newer versions?

Answer №1

Choosing the best JavaScript version depends on the browsers you want to support.

If you still need to cater to older versions like IE, Safari or mobile browsers, stick with es5.

However, if your target audience mostly uses the latest Chrome, Firefox, Edge, or Safari 10, you can consider using es6.

Overall, I recommend sticking with es5 for now.
