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;
}

(from, to) => [...Array(to - from)].map((_,i)=> i + from)

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};

我刚刚通过Object.defineProperty在Array上创建了这个polyfill，以创建整数或字符串的范围。Object.defineProperty是创建polyfills的一种更安全的方法。

更安全的polyfill

if (!Array.range) {
  Object.defineProperty(Array, 'range', {
    value: function (from, to, step) {
      if (typeof from !== 'number' && typeof from !== 'string') {
        throw new TypeError('The first parameter should be a number or a character')
      }

      if (typeof to !== 'number' && typeof to !== 'string') {
        throw new TypeError('The second parameter should be a number or a character')
      }

      var A = []
      if (typeof from === 'number') {
        A[0] = from
        step = step || 1
        while (from + step <= to) {
          A[A.length] = from += step
        }
      } else {
        var s = 'abcdefghijklmnopqrstuvwxyz'
        if (from === from.toUpperCase()) {
          to = to.toUpperCase()
          s = s.toUpperCase()
        }
        s = s.substring(s.indexOf(from), s.indexOf(to) + 1)
        A = s.split('')
      }
      return A
    }
  })
} else {
  var errorMessage = 'DANGER ALERT! Array.range has already been defined on this browser. '
  errorMessage += 'This may lead to unwanted results when Array.range() is executed.'
  console.log(errorMessage)
}

示例

Array.range(1, 3)

// Return: [1, 2, 3]

Array.range(1, 3, 0.5)

// Return: [1, 1.5, 2, 2.5, 3]

Array.range('a', 'c')

// Return: ['a', 'b', 'c']

Array.range('A', 'C')

// Return: ['A', 'B', 'C']

Array.range(null)
Array.range(undefined)
Array.range(NaN)
Array.range(true)
Array.range([])
Array.range({})
Array.range(1, null)

// Return: Uncaught TypeError: The X parameter should be a number or a character

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;
}
