函数范围（firstNum，lastNum）{let rangeList=[]；如果（firstNum>lastNum）{return console.error（“第一个数字不能大于最后一个数字”）；}让counter=firstNum；while（计数器<=lastNum）{rangeList.push（计数器）；计数器++；}返回范围列表；}

根据我的理解：

JS的运行时环境不支持尾部调用优化。编写任何递归函数来生成一个大范围的函数都会给你带来麻烦。如果我们要处理大量数据，那么创建循环数组可能不是最好的做法。写入大循环会导致事件队列变慢。

function range(start, end, step = 1) {
  const _range = _start => f => {
    if (_start < end) {
      f(_start);
      setTimeout(() => _range(_start + step)(f), 0);
    }
  }

  return {
    map: _range(start),
  };
}

range(0, 50000).map(console.log);

此函数不会引发上述问题。

我想补充一点，我认为这是一个非常可调的版本，速度非常快。

const range = (start, end) => {
    let all = [];
    if (typeof start === "string" && typeof end === "string") {
        // Return the range of characters using utf-8 least to greatest
        const s = start.charCodeAt(0);
        const e = end.charCodeAt(0);
        for (let i = s; i <= e; i++) {
            all.push(String.fromCharCode(i));
        }
    } else if (typeof start === "number" && typeof end === "number") {
        // Return the range of numbers from least to greatest
        for(let i = end; i >= start; i--) {
            all.push(i);
        }
    } else {
        throw new Error("Did not supply matching types number or string.");
    }
    return all;
}
// usage
const aTod = range("a", "d");

如果您愿意，也可以使用打字机

const range = (start: string | number, end: string | number): string[] | number[] => {
    const all: string[] | number[] = [];
    if (typeof start === "string" && typeof end === "string") {
        const s: number = start.charCodeAt(0);
        const e: number = end.charCodeAt(0);
        for (let i = s; i <= e; i++) {
            all.push(String.fromCharCode(i));
        }
    } else if (typeof start === "number" && typeof end === "number") {
        for (let i = end; i >= start; i--) {
            all.push(i);
        }
    } else {
        throw new Error("Did not supply matching types number or string.");
    }
    return all;
}
// Usage
const negTenToten: number[] = range(-10, 10) as number[];

受到其他答案的影响。用户已离开。

您可以使用以下一行代码使事情简短明了

var启动=4；var端=20；console.log（数组（end-start+1）.fill（start）.map（（x，y）=>x+y））；

/**
 * @param {!number|[!number,!number]} sizeOrRange Can be the `size` of the range (1st signature) or a
 *   `[from, to]`-shape array (2nd signature) that represents a pair of the *starting point (inclusive)* and the
 *   *ending point (exclusive)* of the range (*mathematically, a left-closed/right-open interval: `[from, to)`*).
 * @param {!number} [fromOrStep] 1st signature: `[from=0]`. 2nd signature: `[step=1]`
 * @param {!number} [stepOrNothing] 1st signature: `[step=1]`. 2nd signature: NOT-BEING-USED
 * @example
 * range(5) ==> [0, 1, 2, 3, 4] // size: 5
 * range(4, 5)    ==> [5, 6, 7, 8]  // size: 4, starting from: 5
 * range(4, 5, 2) ==> [5, 7, 9, 11] // size: 4, starting from: 5, step: 2
 * range([2, 5]) ==> [2, 3, 4] // [2, 5) // from: 2 (inclusive), to: 5 (exclusive)
 * range([1, 6], 2) ==> [1, 3, 5] // from: 1, to: 6, step: 2
 * range([1, 7], 2) ==> [1, 3, 5] // from: 1, to: 7 (exclusive), step: 2
 * @see {@link https://stackoverflow.com/a/72388871/5318303}

export function range (sizeOrRange, fromOrStep, stepOrNothing) {
  let from, to, step, size
  if (sizeOrRange instanceof Array) { // 2nd signature: `range([from, to], step)`
    [from, to] = sizeOrRange
    step = fromOrStep ?? 1
    size = Math.ceil((to - from) / step)
  } else { // 1st signature: `range(size, from, step)`

我的实施

export function stringRange(a: string, b: string) {
    let arr = [a + ''];

    const startPrefix = a.match(/([\D])+/g);
    const endPrefix = b.match(/([\D])+/g);

    if ((startPrefix || endPrefix) && (Array.isArray(startPrefix) && startPrefix[0]) !== (Array.isArray(endPrefix) && endPrefix[0])) {
        throw new Error('Series number does not match');
    }

    const startNum = a.match(/([\d])+/g);
    const endNum = b.match(/([\d])+/g);

    if (!startNum || !endNum) {
        throw new Error('Range is not valid');
    }

    let start = parseInt(startNum[0], 10);
    let end = parseInt(endNum[0], 10);

    if (start > end) {
        throw new Error('Ending value should be lessesr that starting value');
    }

    while (start !== end) {
        start++;
        arr.push(startPrefix ? startPrefix[0] + (start + '').padStart(startNum[0].length, '0') : start + '');

    }

    return arr;
}
