• ES6 (JS2015) features (https://www.w3schools.com/js/js_es6.asp)
  • Just checking that the runtime is ES6. Not testing full features.
  • let, const keyword

    > const x = 1; let y = 2;
    undefined
    > x + y
    3
    

  • Arrow functions

    > const f = (x, y) => x*y;
    undefined
    > f(2,3)
    6
    

• Injected variables
  • console

    > console.log(123); console.error(456);
