您可以使用lodash或Undescore.js范围：

var range = require('lodash/range')
range(10)
// -> [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]

或者，如果您只需要连续的整数范围，则可以执行以下操作：

Array.apply(undefined, { length: 10 }).map(Number.call, Number)
// -> [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]

在ES6范围内，可使用发电机实现：

function* range(start=0, end=null, step=1) {
  if (end == null) {
    end = start;
    start = 0;
  }

  for (let i=start; i < end; i+=step) {
    yield i;
  }
}

这种实现在迭代大型序列时节省了内存，因为它不必将所有值具体化为数组：

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

数字

[...Array(5).keys()];
 => [0, 1, 2, 3, 4]

字符迭代

String.fromCharCode(...[...Array('D'.charCodeAt(0) - 'A'.charCodeAt(0) + 1).keys()].map(i => i + 'A'.charCodeAt(0)));
 => "ABCD"

迭代

for (const x of Array(5).keys()) {
  console.log(x, String.fromCharCode('A'.charCodeAt(0) + x));
}
 => 0,"A" 1,"B" 2,"C" 3,"D" 4,"E"

作为函数

function range(size, startAt = 0) {
    return [...Array(size).keys()].map(i => i + startAt);
}

function characterRange(startChar, endChar) {
    return String.fromCharCode(...range(endChar.charCodeAt(0) -
            startChar.charCodeAt(0), startChar.charCodeAt(0)))
}

类型化函数

function range(size:number, startAt:number = 0):ReadonlyArray<number> {
    return [...Array(size).keys()].map(i => i + startAt);
}

function characterRange(startChar:string, endChar:string):ReadonlyArray<string> {
    return String.fromCharCode(...range(endChar.charCodeAt(0) -
            startChar.charCodeAt(0), startChar.charCodeAt(0)))
}

lodash.js_.range（）函数

_.range(10);
 => [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
_.range(1, 11);
 => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
_.range(0, 30, 5);
 => [0, 5, 10, 15, 20, 25]
_.range(0, -10, -1);
 => [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]
String.fromCharCode(..._.range('A'.charCodeAt(0), 'D'.charCodeAt(0) + 1));
 => "ABCD"

没有库的旧非es6浏览器：

Array.apply(null, Array(5)).map(function (_, i) {return i;});
 => [0, 1, 2, 3, 4]

console.log（[…Array（5）.keys（）]）；

（ES6归功于尼尔斯·彼得索恩和其他评论者）

var range = (l,r) => new Array(r - l).fill().map((_,k) => k + l);

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

这个也反过来。

const range = ( a , b ) => Array.from( new Array( b > a ? b - a : a - b ), ( x, i ) => b > a ? i + a : a - i );

range( -3, 2 ); // [ -3, -2, -1, 0, 1 ]
range( 1, -4 ); // [ 1, 0, -1, -2, -3 ]

我正在分享我的实现，以防它对某人有所帮助。

function Range(start_or_num, end = null, increment = 1) {
    const end_check = end === null
    const start = end_check  ? 0 : start_or_num
    const count = end_check ? start_or_num : Math.round((end - start) / increment) + 1
     const filterFunc = end_check  ?  x => x >= start : x => x < end && x >= start

    return [...Array.from(
        Array(count).keys(), x => increment * (x - 1) + start
    )
    ].filter(filterFunc)
}
// usage
// console.log(Range(4, 10, 2)) // [4, 6, 8]
// console.log(Range(5, 10 )) //[5, 6, 7, 8, 9]
// console.log(Range(10 ))// [0, 1, 2, 3, 4, 5, 6, 7, 8]
