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));

function check(){

    var correct=true;

    for(var i=0; i<arguments.length; i++){

    if(typeof arguments[i] != "number"){

    correct=false;  } } return correct; }   

//------------------------------------------

 function range(start,step,end){

  var correct=check(start,step,end);

  if(correct && (step && end)!=0){ 

  for(var i=start; i<=end; i+=step)

  document.write(i+" "); }

  else document.write("Not Correct Data"); }

var range = (l,r) => new Array(r - l).fill().map((_,k) => k + l);

至于为给定范围生成数字数组，我使用以下方法：

function range(start, stop)
{
    var array = [];

    var length = stop - start; 

    for (var i = 0; i <= length; i++) { 
        array[i] = start;
        start++;
    }

    return array;
}

console.log(range(1, 7));  // [1,2,3,4,5,6,7]
console.log(range(5, 10)); // [5,6,7,8,9,10]
console.log(range(-2, 3)); // [-2,-1,0,1,2,3]

显然，它不适用于字母数组。

使用Harmony排列运算符和箭头函数：

var range = (start, end) => [...Array(end - start + 1)].map((_, i) => start + i);

例子：

range(10, 15);
[ 10, 11, 12, 13, 14, 15 ]

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']
