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']

如果您只想使用范围来重复一个过程n次，您可以简单地使用此代码

[...Array(10)].map((item, index) => ( 
    console.log("item:", index)
))

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[];

受到其他答案的影响。用户已离开。

我刚刚通过Object.defineProperty在Array上创建了这个polyfill，以创建整数或字符串的范围。Object.defineProperty是创建polyfills的一种更安全的方法。

更安全的polyfill

if (!Array.range) {
  Object.defineProperty(Array, 'range', {
    value: function (from, to, step) {
      if (typeof from !== 'number' && typeof from !== 'string') {
        throw new TypeError('The first parameter should be a number or a character')
      }

      if (typeof to !== 'number' && typeof to !== 'string') {
        throw new TypeError('The second parameter should be a number or a character')
      }

      var A = []
      if (typeof from === 'number') {
        A[0] = from
        step = step || 1
        while (from + step <= to) {
          A[A.length] = from += step
        }
      } else {
        var s = 'abcdefghijklmnopqrstuvwxyz'
        if (from === from.toUpperCase()) {
          to = to.toUpperCase()
          s = s.toUpperCase()
        }
        s = s.substring(s.indexOf(from), s.indexOf(to) + 1)
        A = s.split('')
      }
      return A
    }
  })
} else {
  var errorMessage = 'DANGER ALERT! Array.range has already been defined on this browser. '
  errorMessage += 'This may lead to unwanted results when Array.range() is executed.'
  console.log(errorMessage)
}

示例

Array.range(1, 3)

// Return: [1, 2, 3]

Array.range(1, 3, 0.5)

// Return: [1, 1.5, 2, 2.5, 3]

Array.range('a', 'c')

// Return: ['a', 'b', 'c']

Array.range('A', 'C')

// Return: ['A', 'B', 'C']

Array.range(null)
Array.range(undefined)
Array.range(NaN)
Array.range(true)
Array.range([])
Array.range({})
Array.range(1, null)

// Return: Uncaught TypeError: The X parameter should be a number or a character

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
);

// 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
