Javascript提供了一个从给定值创建和填充数组的函数，接收容器数组和映射函数作为参数：

让arr=数组来源（SOURCE_Array，MAP_FUNCTION）；

由于MAP_FUNCTION提供了迭代的值和索引，因此可以创建一个空数组（SOURCE_array）并使用索引填充它，如下所示（supposing 10是您所需的长度）：

let arr=Array.from（数组（10），（n，索引）=>索引）；

输出：[0, 1, 2, 3, 4, 5, 6, 7, 8, 9].

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 ]

// range()              0..10, step=1
// range(max)           0..max, step=1
// range(min,max)       min..max, step=1
// range(min,step,max)  min..max, step=step
// Use:
// console.log(...range(3));
// Array.from(range(5))
// [...range(100)]
// for (const v of range(1,10)) { ... 

function* range(...args) {
    let [min, step, max] = {
        0: [0, 1, 10],
        1: [0, args[0] >= 0 ? 1 : -1, args[0]],
        2: [args[0], args[1] >= args[0] ? 1 : -1, args[1]],
        3: args,
    }[args.length] || [];
    if (min === undefined) throw new SyntaxError("Too many arguments");
    let x = min;
    while (step >= 0 ? x < max : x > max) {
        yield x;
        x += step
    }
}
console.log(...range());      // 0 1 2 3 4 5 6 7 8 9
console.log(...range(3));     // 0 1 2
console.log(...range(2, 5));  // 2 3 4
console.log(...range(5, 2));  // 5 4 3
console.log(...range(3, -3)); // 3 2 1 0 -1 -2
console.log(...range(-3, 3)); // -3 -2 -1 0 1 2
console.log(...range(-5, -2));// -5 -4 -3
console.log(...range(-2, -5));// -2 -3 -4

您还可以执行以下操作：

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

使用这个。它创建了一个具有给定数量的值（未定义）的数组，在下面的示例中有100个索引，但它并不相关，因为这里只需要键。它在数组中使用100+1，因为数组始终基于0索引。因此，如果要生成100个值，则索引从0开始；因此最后的值总是99而不是100。

范围（2100）；功能范围（开始、结束）{console.log（[…Array（end+1）.keys（）].filter（value=>end>=value&&start<=value））；}
