如何用JS快速构建包含0-99整数的数组

var arr = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99];

 

var arr = [];
for(var i = 0; i < 100; i++){
  arr.push(i);
}

 

Object.keys(Array.apply(null, {length:100}));

Object.keys(Array.apply(null, {length: 100})).map(function(item){
  return +item;
})

 

Array.from(new Array(100).keys())

[...Array(100).keys()]
[...Array.from({length:100}).keys()]
