I have this array of objects:

var frequencies = [{id:124,name:'qqq'}, 

                  {id:589,name:'www'}, 

                  {id:45,name:'eee'},

                  {id:567,name:'rrr'}];

I need to get an object from the array above by the id value.

For example I need to get the object with id = 45.

I tried this:

var t = frequencies.map(function (obj) { return obj.id==45; });

But I didn't get the desired object.

How can I implement it using JavaScript prototype functions?

You need filter() not map()

var t = frequencies.filter(function (obj) { 

    return obj.id==45; 

})[0];
