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']

这可能不是最好的方法。但是如果你想在一行代码中得到一系列数字。例如10-50

Array(40).fill(undefined).map((n, i) => i + 10)

其中40是（结束-开始），10是开始。这应该返回[10，11，…，50]

使用TypeScript设置（应用程序范围）：

declare global {
  interface Function {
    range(count: number, start_with: number): number[];
  }
}

Function.prototype.range = function (
  count: number,
  start_with: number = 0
): number[] {
  return [...Array(count).keys()].map((key) => key + start_with);
};

使用JS设置：

Function.prototype.range = function(count, start_with=0){
    return [...Array(count).keys()].map((key) => key + start_with);
}

使用示例：

Function.range(2,0) //Will return [0,1]
Function.range(2,1) //Will return [1,2]
Function.range(2,-1) //Will return [-1,0]

ES6

使用Array.from（此处为文档）：

const range = (start, stop, step) => Array.from({ length: (stop - start) / step + 1}, (_, i) => start + (i * step));

/**
 * @param {!number|[!number,!number]} sizeOrRange Can be the `size` of the range (1st signature) or a
 *   `[from, to]`-shape array (2nd signature) that represents a pair of the *starting point (inclusive)* and the
 *   *ending point (exclusive)* of the range (*mathematically, a left-closed/right-open interval: `[from, to)`*).
 * @param {!number} [fromOrStep] 1st signature: `[from=0]`. 2nd signature: `[step=1]`
 * @param {!number} [stepOrNothing] 1st signature: `[step=1]`. 2nd signature: NOT-BEING-USED
 * @example
 * range(5) ==> [0, 1, 2, 3, 4] // size: 5
 * range(4, 5)    ==> [5, 6, 7, 8]  // size: 4, starting from: 5
 * range(4, 5, 2) ==> [5, 7, 9, 11] // size: 4, starting from: 5, step: 2
 * range([2, 5]) ==> [2, 3, 4] // [2, 5) // from: 2 (inclusive), to: 5 (exclusive)
 * range([1, 6], 2) ==> [1, 3, 5] // from: 1, to: 6, step: 2
 * range([1, 7], 2) ==> [1, 3, 5] // from: 1, to: 7 (exclusive), step: 2
 * @see {@link https://stackoverflow.com/a/72388871/5318303}
 */
export function range (sizeOrRange, fromOrStep, stepOrNothing) {
  let from, to, step, size
  if (sizeOrRange instanceof Array) { // 2nd signature: `range([from, to], step)`
    [from, to] = sizeOrRange
    step = fromOrStep ?? 1
