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））；}

我想补充一点，我认为这是一个非常可调的版本，速度非常快。

const range = (start, end) => {
    let all = [];
    if (typeof start === "string" && typeof end === "string") {
        // Return the range of characters using utf-8 least to greatest
        const s = start.charCodeAt(0);
        const e = end.charCodeAt(0);
        for (let i = s; i <= e; i++) {
            all.push(String.fromCharCode(i));
        }
    } else if (typeof start === "number" && typeof end === "number") {
        // Return the range of numbers from least to greatest
        for(let i = end; i >= start; i--) {
            all.push(i);
        }
    } else {
        throw new Error("Did not supply matching types number or string.");
    }
    return all;
}
// usage
const aTod = range("a", "d");

如果您愿意，也可以使用打字机

const range = (start: string | number, end: string | number): string[] | number[] => {
    const all: string[] | number[] = [];
    if (typeof start === "string" && typeof end === "string") {
        const s: number = start.charCodeAt(0);
        const e: number = end.charCodeAt(0);
        for (let i = s; i <= e; i++) {
            all.push(String.fromCharCode(i));
        }
    } else if (typeof start === "number" && typeof end === "number") {
        for (let i = end; i >= start; i--) {
            all.push(i);
        }
    } else {
        throw new Error("Did not supply matching types number or string.");
    }
    return all;
}
// Usage
const negTenToten: number[] = range(-10, 10) as number[];

要紧密复制的类型脚本函数

export function range(

export function* range(a: unknown, b?: unknown, c?: unknown): Iterable<number> {
  const getNumber = (val: unknown): number =>
    typeof val === 'number' ? val : (val as BigNumber).toNumber()
  const getStart = () => (b === undefined ? 0 : getNumber(a))
  const getStop = () => (b === undefined ? getNumber(a) : getNumber(b))
  const getStep = () => (c === undefined ? 1 : getNumber(c))

  for (let i = getStart(); i < getStop(); i += getStep()) {
    yield i
  }
}

也可以使用生成器生成序列。不同之处在于序列中的每个值都是延迟加载的。spread运算符和for为结果工作。星号符号使函数成为生成器。

const range = function*(from,to) {   
    for(let i = from; i <= to; i++) yield I;   
};   

[...range(3,5)]// => [3, 4, 5]

(from, to) => [...Array(to - from)].map((_,i)=> i + from)

可以如下创建大量使用ES6的相当简约的实现，特别注意Array.from（）静态方法：

const getRange = (start, stop) => Array.from(
  new Array((stop - start) + 1),
  (_, i) => i + start
);
