您还可以执行以下操作：

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

在边界内生成整数数组的递归解决方案。

function intSequence(start, end, n = start, arr = []) {
  return (n === end) ? arr.concat(n)
    : intSequence(start, end, start < end ? n + 1 : n - 1, arr.concat(n));
}

$> intSequence(1, 1)
<- Array [ 1 ]

$> intSequence(1, 3)
<- Array(3) [ 1, 2, 3 ]

$> intSequence(3, -3)
<- Array(7) [ 3, 2, 1, 0, -1, -2, -3 ]

也可以使用生成器生成序列。不同之处在于序列中的每个值都是延迟加载的。spread运算符和for为结果工作。星号符号使函数成为生成器。

const range = function*(from,to) {   
    for(let i = from; i <= to; i++) yield I;   
};   

[...range(3,5)]// => [3, 4, 5]

它适用于字符和数字，通过可选步骤向前或向后移动。

var range = function(start, end, step) {
    var range = [];
    var typeofStart = typeof start;
    var typeofEnd = typeof end;

    if (step === 0) {
        throw TypeError("Step cannot be zero.");
    }

    if (typeofStart == "undefined" || typeofEnd == "undefined") {
        throw TypeError("Must pass start and end arguments.");
    } else if (typeofStart != typeofEnd) {
        throw TypeError("Start and end arguments must be of same type.");
    }

    typeof step == "undefined" && (step = 1);

    if (end < start) {
        step = -step;
    }

    if (typeofStart == "number") {

        while (step > 0 ? end >= start : end <= start) {
            range.push(start);
            start += step;
        }

    } else if (typeofStart == "string") {

        if (start.length != 1 || end.length != 1) {
            throw TypeError("Only strings with one character are supported.");
        }

        start = start.charCodeAt(0);
        end = end.charCodeAt(0);

        while (step > 0 ? end >= start : end <= start) {
            range.push(String.fromCharCode(start));
            start += step;
        }

    } else {
        throw TypeError("Only string and number types are supported");
    }

    return range;

}

jsFiddle。

如果扩充本机类型是您的事情，那么将其分配给Array.range。

var范围=函数（开始、结束、步骤）{var范围=[]；var typeofStart=启动类型；var typeofEnd=结束类型；如果（步骤==0）{throw TypeError（“步长不能为零。”）；}if（类型开始==“undefined”| |类型结束==“未定义”）{throw TypeError（“必须传递开始和结束参数。”）；}否则如果（typeofStart！=typeofEnd）{throw TypeError（“开始和结束参数必须是相同的类型。”）；}步骤类型==“未定义”&&（步骤=1）；if（结束<开始）{step=-步骤；}if（开始类型==“number”）{while（步骤>0？结束>=开始：结束<=开始）{范围.推（启动）；开始+=步骤；}}否则if（typeofStart==“string”）{如果（start.length！=1 | | end.length；=1）{throw TypeError（“仅支持带有一个字符的字符串。”）；}start=start.charCodeAt（0）；end=end.charCodeAt（0）；while（步骤>0？结束>=开始：结束<=开始）{range.push（String.fromCharCode（开始））；开始+=步骤；}}其他{throw TypeError（“仅支持字符串和数字类型”）；}返回范围；}console.log（范围（“A”，“Z”，1））；console.log（范围（“Z”，“A”，1））；console.log（范围（“A”，“Z”，3））；console.log（范围（0，25，1））；console.log（范围（0，25，5））；console.log（范围（20，5，5））；

一个定义了硬整数的范围有很多答案，但是如果你不知道这一步，而你想在这一步之间多走几步呢？

我写这段代码就是为了做到这一点。这很不言自明。

const stepScale = (min, max, numberOfSteps) => {
  const _numberOfSteps = numberOfSteps - 1
  const scaleBy = (max - min) / _numberOfSteps

  const arr = []
  for (let i = 0; i <= _numberOfSteps; i += 1) {
    arr.push(min + scaleBy * i)
  }
  return arr
}

export default stepScale

stepScale(5, 10, 4)
// [5, 6.666666666666667, 8.333333333333334, 10]
