Difference in the 'lib' property in tsconfig.json between es6 and es2017?

Question

I\'ve been researching what the possible values of the lib property mean in the compilerOptions found within the tsconfig.json file. I fou

Answer 1

After some digging and comparing through the lib folder on the Typescript GitHub I have found that, using es6 in the lib property in the compilerOptions corresponds to the code found in these references:

/// <reference path="lib.es2015.core.d.ts" />
/// <reference path="lib.es2015.collection.d.ts" />
/// <reference path="lib.es2015.generator.d.ts" />
/// <reference path="lib.es2015.iterable.d.ts" />
/// <reference path="lib.es2015.promise.d.ts" />
/// <reference path="lib.es2015.proxy.d.ts" />
/// <reference path="lib.es2015.reflect.d.ts" />
/// <reference path="lib.es2015.symbol.d.ts" />
/// <reference path="lib.es2015.symbol.wellknown.d.ts" />
/// <reference path="lib.es5.d.ts" />
/// <reference path="lib.dom.d.ts" />
/// <reference path="lib.scripthost.d.ts.d.ts" />
/// <reference path="lib.dom.iterable.d.ts" />

so to answer my question, to correctly cover all the contents of es6 with es2017 that section of the tsconfig.json should look like this:

{
  ...
  "compilerOptions": {
    ...
    "lib": ["es2017", "dom", "dom.iterable", "scripthost"]
  },
  ...
  }
}
