对于行为类似python range（）函数的函数，请使用以下命令：

function range(min=0, max=null){
    if(max === null){
        max=min;
        min=0;
    }
    var rg=[...Array(max).keys()];
    return rg.slice(min,max);
}   

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[];

我发现了一个与PHP中的函数相当的JS范围函数，在这里工作得非常棒。向前和向后工作，可以处理整数、浮点数和字母！

function range(low, high, step) {
  //  discuss at: http://phpjs.org/functions/range/
  // original by: Waldo Malqui Silva
  //   example 1: range ( 0, 12 );
  //   returns 1: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
  //   example 2: range( 0, 100, 10 );
  //   returns 2: [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
  //   example 3: range( 'a', 'i' );
  //   returns 3: ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i']
  //   example 4: range( 'c', 'a' );
  //   returns 4: ['c', 'b', 'a']

  var matrix = [];
  var inival, endval, plus;
  var walker = step || 1;
  var chars = false;

  if (!isNaN(low) && !isNaN(high)) {
    inival = low;
    endval = high;
  } else if (isNaN(low) && isNaN(high)) {
    chars = true;
    inival = low.charCodeAt(0);
    endval = high.charCodeAt(0);
  } else {
    inival = (isNaN(low) ? 0 : low);
    endval = (isNaN(high) ? 0 : high);
  }

  plus = ((inival > endval) ? false : true);
  if (plus) {
    while (inival <= endval) {
      matrix.push(((chars) ? String.fromCharCode(inival) : inival));
      inival += walker;
    }
  } else {
    while (inival >= endval) {
      matrix.push(((chars) ? String.fromCharCode(inival) : inival));
      inival -= walker;
    }
  }

  return matrix;
}

这是缩小版：

function range(h,c,b){var i=[];var d,f,e;var a=b||1;var g=false;if(!isNaN(h)&&!isNaN(c)){d=h;f=c}else{if(isNaN(h)&&isNaN(c)){g=true;d=h.charCodeAt(0);f=c.charCodeAt(0)}else{d=(isNaN(h)?0:h);f=(isNaN(c)?0:c)}}e=((d>f)?false:true);if(e){while(d<=f){i.push(((g)?String.fromCharCode(d):d));d+=a}}else{while(d>=f){i.push(((g)?String.fromCharCode(d):d));d-=a}}return i};

至于为给定范围生成数字数组，我使用以下方法：

function range(start, stop)
{
    var array = [];

    var length = stop - start; 

    for (var i = 0; i <= length; i++) { 
        array[i] = start;
        start++;
    }

    return array;
}

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

显然，它不适用于字母数组。

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]
