ES6 as a typescript compiler option for angularjs or angular2

Question

The compiler option for my angularjs application is given below. Should I use any other package to redirect es6 to es5 if I change the target to es6 ?

    {
      "compilerOptions": {
        "target": "es5", // Change this to es6
        "module": "commonjs",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false,
        "outDir": "./wwwroot/app/"
      },
      "exclude": [
        "node_modules",
        "wwwroot"
      ]
    }
