Op要求范围，例如范围（3，10），因此可以

[...[...Array(10-3).keys()].map(i => i+3)]

回报

[3, 4, 5, 6, 7, 8, 9]

这是我的2美分：

function range(start, end) {
  return Array.apply(0, Array(end - 1))
    .map((element, index) => index + start);
}

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

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）

已经给出了非常好的答案，但我没有看到ES6迭代器的完整使用来实现范围的完整实现，所以这里是：

/**
 * inspired by Python's built-in range utility function
 * implemented using ES6 Iterable, Iterator  protolols (interfaces)
 */
class Range {
  constructor(...args) {
    this.start = args.length <= 1 ? 0 : args[0];
    this.end = args.length <= 1 ? args[0] || 0 : args[1];
    this.step = args.length <= 2 ? 1 : args[2];
  }

  [Symbol.iterator]() {
    return this;
  }

  next() {
    if (this.end > this.start) {
      const result = { done: false, value: this.start };
      this.start = this.start + this.step;
      return result;
    } else return { done: true, value: undefined };
  }
}

/**
 * Symbol.iterator is part of the couple of inbuilt symbols
 * available in JavaScript. It allows for hooking into the
 * inbuilt for of iteration mechanism. This is why the
 * Symbol.iterator comes into play when talking about
 * iterables and iterators in JavaScript.
 */

function range(...args) {
  return new Range(...args);
}

console.log([...range(4)]);        // [0, 1, 2, 3]
console.log([...range(2, 5)]);     // [2, 3, 4]
console.log([...range(1, 10, 3)]); // [1, 4, 7]

尚未实施！

使用新的Number.range建议（第1阶段）：

[...Number.range(1, 10)]
//=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
