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]);
        })
    })
})

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]

这是我模仿Python的解决方案。在底部，您可以找到一些如何使用它的示例。它与数字一起工作，就像Python的范围一样：

var assert = require('assert');    // if you use Node, otherwise remove the asserts

var L = {};    // L, i.e. 'list'

// range(start, end, step)
L.range = function (a, b, c) {
    assert(arguments.length >= 1 && arguments.length <= 3);
    if (arguments.length === 3) {
        assert(c != 0);
    }

    var li = [],
        i,
        start, end, step,
        up = true;    // Increasing or decreasing order? Default: increasing.

    if (arguments.length === 1) {
        start = 0;
        end = a;
        step = 1;
    }

    if (arguments.length === 2) {
        start = a;
        end = b;
        step = 1;
    }

    if (arguments.length === 3) {
        start = a;
        end = b;
        step = c;
        if (c < 0) {
            up = false;
        }
    }

    if (up) {
        for (i = start; i < end; i += step) {
            li.push(i);
        }
    } else {
        for (i = start; i > end; i += step) {
            li.push(i);
        }
    }

    return li;
}

示例：

// range
L.range(0) -> []
L.range(1) -> [0]
L.range(2) -> [0, 1]
L.range(5) -> [0, 1, 2, 3, 4]

L.range(1, 5) -> [1, 2, 3, 4]
L.range(6, 4) -> []
L.range(-2, 2) -> [-2, -1, 0, 1]

L.range(1, 5, 1) -> [1, 2, 3, 4]
L.range(0, 10, 2) -> [0, 2, 4, 6, 8]
L.range(10, 2, -1) -> [10, 9, 8, 7, 6, 5, 4, 3]
L.range(10, 2, -2) -> [10, 8, 6, 4]

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）

这里有一个基于@benmcdonald和其他人的简单方法，尽管不止一行。。。

设K=[]；对于（i=“A”.charCodeAt（0）；i<=“Z”.charCodeAt（0）；i++）{K.push（字符串来自CharCode（i））};console.log（K）；

这是我用于数字范围的方法：

const rangeFrom0 = end => [...Array(end)].map((_, index) => index);

or

const rangeExcEnd = (start, step, end) => [...Array(end - start + 1)]
   .map((_, index) => index + start)
   .filter(x => x % step === start % step);
