我的代码高尔夫同事想出了这个（ES6），包容的：

(s,f)=>[...Array(f-s+1)].map((e,i)=>i+s)

非包容性：

(s,f)=>[...Array(f-s)].map((e,i)=>i+s)

编码为2010年规格（是的，2016年是ES6发电机）。这是我的想法，其中包含模拟Python的range（）函数的选项。

Array.range = function(start, end, step){
    if (start == undefined) { return [] } // "undefined" check

    if ( (step === 0) )  {  return []; // vs. throw TypeError("Invalid 'step' input")
    }  // "step" == 0  check

    if (typeof start == 'number') { // number check
        if (typeof end == 'undefined') { // single argument input
            end = start;
            start = 0;
            step = 1;
        }
        if ((!step) || (typeof step != 'number')) {
          step = end < start ? -1 : 1;
        }

        var length = Math.max(Math.ceil((end - start) / step), 0);
        var out = Array(length);

        for (var idx = 0; idx < length; idx++, start += step) {
          out[idx] = start;
        }

        // Uncomment to check "end" in range() output, non pythonic
        if ( (out[out.length-1] + step) == end ) { // "end" check
            out.push(end)
        }

    } else { 
        // Historical: '&' is the 27th letter: http://nowiknow.com/and-the-27th-letter-of-the-alphabet/
        // Axiom: 'a' < 'z' and 'z' < 'A'
        // note: 'a' > 'A' == true ("small a > big A", try explaining it to a kid! )

        var st = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ&'; // axiom ordering

        if (typeof end == 'undefined') { // single argument input
            end = start;
            start = 'a';
        }

        var first = st.indexOf(start);
        var last = st.indexOf(end);

        if ((!step) || (typeof step != 'number')) {
          step = last < first ? -1 : 1;
        }

        if ((first == -1) || (last == -1 )) { // check 'first' & 'last'
            return []
        }

        var length = Math.max(Math.ceil((last - first) / step), 0);
        var out = Array(length);

        for (var idx = 0; idx < length; idx++, first += step) {
          out[idx] = st[first];
        } 

        // Uncomment to check "end" in range() output, non pythonic
        if ( (st.indexOf(out[out.length-1]) + step ) == last ) { // "end" check
            out.push(end)
        }
    }
    return out;
}

例子：

Array.range(5);       // [0,1,2,3,4,5]
Array.range(4,-4,-2); // [4, 2, 0, -2, -4]
Array.range('a','d'); // ["a", "b", "c", "d"]
Array.range('B','y'); // ["B", "A", "z", "y"], different from chr() ordering
Array.range('f');     // ["a", "b", "c", "d", "e", "f"]
Array.range(-5);      // [], similar to python
Array.range(-5,0)     // [-5,-4-,-3-,-2,-1,0]

您还可以执行以下操作：

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

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

好的，在JavaScript中，我们没有像PHP那样的range（）函数，所以我们需要创建一个非常简单的函数

对于数字：

function numberRange (start, end) {
  return new Array(end - start).fill().map((d, i) => i + start);
}

并将其称为：

numberRange(5, 10); //[5, 6, 7, 8, 9]

对于字母：

function alphabetRange (start, end) {
  return new Array(end.charCodeAt(0) - start.charCodeAt(0)).fill().map((d, i) => String.fromCharCode(i + start.charCodeAt(0)));
}

并将其称为：

alphabetRange('c', 'h'); //["c", "d", "e", "f", "g"]

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 ]
