---更新（感谢@lokhmakov简化）---

另一个使用ES6发生器的版本（参见伟大的Paolo Moretti回答ES6发生器）：

const RANGE = (x,y) => Array.from((function*(){
  while (x <= y) yield x++;
})());

console.log(RANGE(3,7));  // [ 3, 4, 5, 6, 7 ]

或者，如果我们只需要可迭代，那么：

const RANGE_ITER = (x,y) => (function*(){
  while (x <= y) yield x++;
})();

for (let n of RANGE_ITER(3,7)){
  console.log(n);
}

// 3
// 4
// 5
// 6
// 7

---原始代码为：---

const RANGE = (a,b) => Array.from((function*(x,y){
  while (x <= y) yield x++;
})(a,b));

and

const RANGE_ITER = (a,b) => (function*(x,y){
  while (x <= y) yield x++;
})(a,b);

我刚刚通过Object.defineProperty在Array上创建了这个polyfill，以创建整数或字符串的范围。Object.defineProperty是创建polyfills的一种更安全的方法。

更安全的polyfill

if (!Array.range) {
  Object.defineProperty(Array, 'range', {
    value: function (from, to, step) {
      if (typeof from !== 'number' && typeof from !== 'string') {
        throw new TypeError('The first parameter should be a number or a character')
      }

      if (typeof to !== 'number' && typeof to !== 'string') {
        throw new TypeError('The second parameter should be a number or a character')
      }

      var A = []
      if (typeof from === 'number') {
        A[0] = from
        step = step || 1
        while (from + step <= to) {
          A[A.length] = from += step
        }
      } else {
        var s = 'abcdefghijklmnopqrstuvwxyz'
        if (from === from.toUpperCase()) {
          to = to.toUpperCase()
          s = s.toUpperCase()
        }
        s = s.substring(s.indexOf(from), s.indexOf(to) + 1)
        A = s.split('')
      }
      return A
    }
  })
} else {
  var errorMessage = 'DANGER ALERT! Array.range has already been defined on this browser. '
  errorMessage += 'This may lead to unwanted results when Array.range() is executed.'
  console.log(errorMessage)
}

示例

Array.range(1, 3)

// Return: [1, 2, 3]

Array.range(1, 3, 0.5)

// Return: [1, 1.5, 2, 2.5, 3]

Array.range('a', 'c')

// Return: ['a', 'b', 'c']

Array.range('A', 'C')

// Return: ['A', 'B', 'C']

Array.range(null)
Array.range(undefined)
Array.range(NaN)
Array.range(true)
Array.range([])
Array.range({})
Array.range(1, null)

// Return: Uncaught TypeError: The X parameter should be a number or a character

我个人最喜欢的：

const range = (start, end) => new Array(end-start+1).fill().map((el, ind) => ind + start);

我找到的最接近的是radash图书馆：

import { range } from 'radash'

for (let i of range(1, 5)) {
    console.log(i)
}

请参阅此处的文档：

范围Radash

// range()              0..10, step=1
// range(max)           0..max, step=1
// range(min,max)       min..max, step=1
// range(min,step,max)  min..max, step=step
// Use:
// console.log(...range(3));
// Array.from(range(5))
// [...range(100)]
// for (const v of range(1,10)) { ... 

function* range(...args) {
    let [min, step, max] = {
        0: [0, 1, 10],
        1: [0, args[0] >= 0 ? 1 : -1, args[0]],
        2: [args[0], args[1] >= args[0] ? 1 : -1, args[1]],
        3: args,
    }[args.length] || [];
    if (min === undefined) throw new SyntaxError("Too many arguments");
    let x = min;
    while (step >= 0 ? x < max : x > max) {
        yield x;
        x += step
    }
}
console.log(...range());      // 0 1 2 3 4 5 6 7 8 9
console.log(...range(3));     // 0 1 2
console.log(...range(2, 5));  // 2 3 4
console.log(...range(5, 2));  // 5 4 3
console.log(...range(3, -3)); // 3 2 1 0 -1 -2
console.log(...range(-3, 3)); // -3 -2 -1 0 1 2
console.log(...range(-5, -2));// -5 -4 -3
console.log(...range(-2, -5));// -2 -3 -4

保持简单：

// Generator
function* iter(a, b, step = 1) {
  for (let i = b ? a : 0; i < (b || a); i += step) {
    yield i
  }
}

const range = (a, b, step = 1) =>
  typeof a === 'string'
    ? [...iter(a.charCodeAt(), b.charCodeAt() + 1)].map(n => String.fromCharCode(n))
    : [...iter(a, b, step)]

range(4) // [0, 1, 2, 3]
range(1, 4) // [1, 2, 3]
range(2, 20, 3) // [2, 5, 8, 11, 14, 17]
range('A', 'C') // ['A', 'B', 'C']
