这个也反过来。

const range = ( a , b ) => Array.from( new Array( b > a ? b - a : a - b ), ( x, i ) => b > a ? i + a : a - i );

range( -3, 2 ); // [ -3, -2, -1, 0, 1 ]
range( 1, -4 ); // [ 1, 0, -1, -2, -3 ]

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;
}

样本结果

// console.log(range('0', '10'));
// console.log(range('10', '10')); 
// console.log(range('10', '20'));
// console.log(range('10', '20000'));
// console.log(range('ABC10', 'ABC23'));
// console.log(range('ABC10', 'ABC2300'));
// console.log(range('ABC10', 'ABC09')); --> Failure case
// console.log(range('10', 'ABC23')); --> Failure case
// console.log(range('ABC10', '23')); --> Failure case

使用Harmony排列运算符和箭头函数：

var range = (start, end) => [...Array(end - start + 1)].map((_, i) => start + i);

例子：

range(10, 15);
[ 10, 11, 12, 13, 14, 15 ]

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);

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。

function check(){

    var correct=true;

    for(var i=0; i<arguments.length; i++){

    if(typeof arguments[i] != "number"){

    correct=false;  } } return correct; }   

//------------------------------------------

 function range(start,step,end){

  var correct=check(start,step,end);

  if(correct && (step && end)!=0){ 

  for(var i=start; i<=end; i+=step)

  document.write(i+" "); }

  else document.write("Not Correct Data"); }
