arrows

  • func shorthand

    • classes

  • sugar over JavaScript's existing prototype-based inheritance
  • provide a much simpler and clearer syntax to create objects and deal with inheritance.

    • destructuring

  • makes it possible to extract data from arrays or objects into distinct variables.

    • let / const

  • `let` is the new `var`

    • template string

  • like string interpolation

    • default / rest / spread parameter

    for...of

  • similar to for each...in

    • Thanks!
