Use the delete operator:

var ob = {w74: {number: 1}, w100: {number: 2},w12: {number: 3},w3: {number: 4}};
console.log(ob);
delete ob.w74;
console.log(ob);

You can directly delete your value from object by key value

eg.

  var arrChildOptions2 = {
       w74: Object, w100: Object,w12: Object,w3: Object
     };

delete arrChildOptions2.w12;

Use underscore library function called _.pick() http://underscorejs.org/#pick

_.pick({name: 'moe', age: 50, userid: 'moe1'}, 'name', 'age');
=> {name: 'moe', age: 50}

_.pick({name: 'moe', age: 50, userid: 'moe1'}, function(value, key, object) {
  return _.isNumber(value);
});
=> {age: 50}
