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.

• Suresh Atta: x =<numGroups should be x <=numGroups
• RobG: Where is AD_GROUP_NAMES defined?
• Vivick: array traversal for loop : for(var i = 0 ; i < arr.length ; i++)
• Nina Scholz: what result do you expect?

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);
