简单范围函数：

function range(start, stop, step) {
    var a = [start], b = start;
    while (b < stop) {
        a.push(b += step || 1);
    }
    return a;
}

要合并BigInt数据类型，可以包括一些检查，以确保所有变量都是相同的开始类型：

function range(start, stop, step) {
    var a = [start], b = start;
    if (typeof start == 'bigint') {
        stop = BigInt(stop)
        step = step? BigInt(step): 1n;
    } else
        step = step || 1;
    while (b < stop) {
        a.push(b += step);
    }
    return a;
}

要删除高于停止定义的值，例如范围（0,5,2）将包括6，但不应是。

function range(start, stop, step) {
    var a = [start], b = start;
    while (b < stop) {
        a.push(b += step || 1);
    }
    return (b > stop) ? a.slice(0,-1) : a;
}

您还可以执行以下操作：

const range = Array.from(Array(size)).map((el, idx) => idx+1).slice(begin, end);

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([]);
    })

    describe('step=1', () => {
        it('normal', () => {
            expect(range(6,12)).toMatchObject([6, 7, 8, 9, 10, 11]);
        })

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

    describe('step=5', () => {

        it('start 0 end 60', () => {
            expect(range(0, 60, 5)).toMatchObject([0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55]);
        })

        it('reversed start 60 end -1', () => {
            expect(range(55, -1, 5)).toMatchObject([55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0]);
        })
    })
})

要紧密复制的类型脚本函数

export function range(
  start: number | BigNumber,
  stop: number | BigNumber,
  step: number | BigNumber,

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
  }
}

这里是一个范围函数的定义，它的行为与Python的范围类型完全相同，只是这个函数不是懒惰的。把它变成发电机应该很容易。

范围构造函数的参数必须是数字。如果省略step参数，则默认为1。如果省略了start参数，则默认为0。如果步骤为零，则会引发错误。

range = (start, stop, step=1) => {
    if(step === 0) throw new Error("range() arg 3 must not be zero");

    const noStart = stop == null;
    stop = noStart ? start : stop;
    start = noStart ? 0 : start;
    const length = Math.ceil(((stop - start) / step));

    return Array.from({length}, (_, i) => (i * step) + start);
}

console.log(range(-10, 10, 2));
//output [Array] [-10,-8,-6,-4,-2,0,2,4,6,8]
console.log(range(10));
// [Array] [0,1,2,3,4,5,6,7,8,9]
console.log(3, 12);
// [Array] [3,4,5,6,7,8,9,10,11]

Array.from(Array((m - n + 1)), (v, i) => n + i); // m > n and both of them are integers.
