我喜欢下面的路

var范围=函数（x，y）{return数组（y-x+1）.fill（x）.map（（a，b）=>{return a+b}）.filter（i=>i>=x）；};console.log（范围（3，10））；

如果在Visual Studio代码中遇到以下错误：

类型“IterableIterator”不是数组类型或字符串类型。使用编译器选项“--downloadIteration”允许迭代迭代器。

而不是

[...Array(3).keys()]

你可以信赖

Array.from(Array(3).keys())

有关下层迭代的更多信息

我正在分享我的实现，以防它对某人有所帮助。

function Range(start_or_num, end = null, increment = 1) {
    const end_check = end === null
    const start = end_check  ? 0 : start_or_num
    const count = end_check ? start_or_num : Math.round((end - start) / increment) + 1
     const filterFunc = end_check  ?  x => x >= start : x => x < end && x >= start

    return [...Array.from(
        Array(count).keys(), x => increment * (x - 1) + start
    )
    ].filter(filterFunc)
}
// usage
// console.log(Range(4, 10, 2)) // [4, 6, 8]
// console.log(Range(5, 10 )) //[5, 6, 7, 8, 9]
// console.log(Range(10 ))// [0, 1, 2, 3, 4, 5, 6, 7, 8]

要紧密复制的类型脚本函数

nope-在2002年仍然没有原生javascript范围，但这个简洁的ES6箭头函数可以像PHP一样提供升序和降序的数字和字符串（包括步骤）。

//@return数字或字符串的升序或降序范围常量范围=（a，b，d=1）=>类型a==“字符串”? range（a.charCodeAt（），b.charCodeAt（））.map（v=>String.fromCharCode（v））：isNaN（b）? 范围（0，a-1）：b<a? 范围（b，a，d）反向（）：d>1? 范围（a，b）。过滤器（v=>v%d==0）：[a，b].reduce（（min，max）=>阵列（max+1-min）.填充（min）.map（（v，i）=>v+i））；//用途控制台断言(range（3）.toString（）=='0,1,2'&&range（2,4）.toString（）==“2,3,4”&&range（4,2）.toString（）=='4,3,2'&&范围（5,15,5）.toString（）=='5,10,15'&&range（'A'，'C'）.toString（）==“A，B，C”&&range（'C'，'A'）.toString（）=='C，B，A');
