可以如下创建大量使用ES6的相当简约的实现，特别注意Array.from（）静态方法：

const getRange = (start, stop) => Array.from(
  new Array((stop - start) + 1),
  (_, i) => i + start
);

使用Harmony排列运算符和箭头函数：

var range = (start, end) => [...Array(end - start + 1)].map((_, i) => start + i);

例子：

range(10, 15);
[ 10, 11, 12, 13, 14, 15 ]

如果在Visual Studio代码中遇到以下错误：

类型“IterableIterator”不是数组类型或字符串类型。使用编译器选项“--downloadIteration”允许迭代迭代器。

而不是

[...Array(3).keys()]

你可以信赖

Array.from(Array(3).keys())

有关下层迭代的更多信息

没有本机方法。但您可以使用Array的过滤方法来实现。

var范围=（数组，开始，结束）=>array.filter（（元素，索引）=>索引>=开始和索引<=结束）警报（范围（['a'，'h'，'e'，'l'，'''，'o'，'s']，1,5））//['h'，'e'，'l'，'o']

要紧密复制的类型脚本函数

export function* range(a: unknown, b?: unknown, c?: unknown): Iterable<number> {
  const getNumber = (val: unknown): number =>
    typeof val === 'number' ? val : (val as BigNumber).toNumber()
  const getStart = () => (b === undefined ? 0 : getNumber(a))
  const getStop = () => (b === undefined ? getNumber(a) : getNumber(b))
  const getStep = () => (c === undefined ? 1 : getNumber(c))

  for (let i = getStart(); i < getStop(); i += getStep()) {
    yield i
  }
}

没有一个示例进行了测试，每个步骤都有一个生成递减值的选项。

export function range(start = 0, end = 0, step = 1) {
    if (start === end || step === 0) {
        return [];
    }

    const diff = Math.abs(end - start);
    const length = Math.ceil(diff / step);

    return start > end
        ? Array.from({length}, (value, key) => start - key * step)
        : Array.from({length}, (value, key) => start + key * step);

}

测验：

import range from './range'

describe('Range', () => {
    it('default', () => {
        expect(range()).toMatchObject([]);
    })

    it('same values', () => {
        expect(range(1,1)).toMatchObject([]);
    })

    it('step=0', () => {
        expect(range(0,1,0)).toMatchObject([]);
    })

            expect(range(6,12)).toMatchObject([6, 7, 8, 9, 10, 11]);
        })

        it('reversed', () => {
            expect(range(12,6)).toMatchObject([12, 11, 10, 9, 8, 7]);
        })
    })
