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 ]

这是我的2美分：

function range(start, end) {
  return Array.apply(0, Array(end - 1))
    .map((element, index) => index + start);
}

Array.range = function(a, b, step){
    var A = [];
    if(typeof a == 'number'){
        A[0] = a;
        step = step || 1;
        while(a+step <= b){
            A[A.length]= a+= step;
        }
    }
    else {
        var s = 'abcdefghijklmnopqrstuvwxyz';
        if(a === a.toUpperCase()){
            b = b.toUpperCase();
            s = s.toUpperCase();
        }
        s = s.substring(s.indexOf(a), s.indexOf(b)+ 1);
        A = s.split('');        
    }
    return A;
}
    
    
Array.range(0,10);
// [0,1,2,3,4,5,6,7,8,9,10]
    
Array.range(-100,100,20);
// [-100,-80,-60,-40,-20,0,20,40,60,80,100]
    
Array.range('A','F');
// ['A','B','C','D','E','F')
    
Array.range('m','r');
// ['m','n','o','p','q','r']

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

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。

Array.from(Array((m - n + 1)), (v, i) => n + i); // m > n and both of them are integers.
