Creating object in a for loop syntax error

Question

I am getting a syntax error on the following code for the line where I define the object within the for loop. What is going wrong here?

var NAMES     = [ 'Accessories', 'Basins' ];      
var VARIANTS  = [ ['red','green','blue'], ['red','green','blue'] ];  
var numGroups = AD_GROUP_NAMES.length;
var INFO      = [];

for (var x = 0; x =< numGroups; x++) {
    var obj = { name : NAMES[x], variants : VARIANTS[x] };
    INFO.push(obj);
}

Any ideas? Any help appreciated.

Change comparison operator from =< to >=.

Also you should set numGroups to length - 1: var numGroups = AD_GROUP_NAMES.length - 1;

var NAMES     = [ 'Accessories', 'Basins' ];      
var VARIANTS  = [ ['red','green','blue'], ['red','green','blue'] ];  
var numGroups = 1 ;//AD_GROUP_NAMES.length - 1;
var INFO      = [];

for (var x = 0; x <= numGroups; x++) {
    var obj = { name : NAMES[x], variants : VARIANTS[x] };
    INFO.push(obj);
}

console.log(INFO);

Please don't reference w3schools, use either ECMA-262 or MDN.
