split versus spread

Setup

function _toConsumableArray(arr) { if (Array.isArray(arr)) { for (var i = 0, arr2 = Array(arr.length); i < arr.length; i++) { arr2[i] = arr[i]; } return arr2; } else { return Array.from(arr); } }

var a = 'hello'

Tests

  • spread

    var c = [].concat(_toConsumableArray(a))
  • split

    var d = a.split('')
