udaykanth, I would say that a .forEach() would be the most common and most basic use of a callback function. I'm just writing this to help anyone that might have a hard time thinking up a quick example if the come across this question themselves. Example: var numArray = [ 1, 2, 3 ] ; numArray.forEach( function( i ) { console.log( arr[ i - 1 ] ) } ) ; // logs out // 1 // 2 // 3

I don't think Bloomberg is a very good company. I am an excellent web developer and have gotten multiple offers from other companies with big names, but was rejected by Bloomberg. They are too demanding during the job interview and it becomes a game of how well you can interview as opposed to how talented an employee you are and how much you can contribute to the growth of the company.

Is there a front end role at bloomberg. I guess your position must have been labelled software dev right? altho ur a dront end dev

5 vote down star 4 I understand passing in a function to another function as a callback and having it execute, but I'm not understanding the best implementation to do that. I'm looking for a very basic example, like this: var myCallBackExample = { myFirstFunction : function( param1, param2, callback ) { // Do something with param1 and param2. if ( arguments.length == 3 ) { // Execute callback function. // What is the "best" way to do this? } }, mySecondFunction : function() { myFirstFunction( false, true, function() { // When this anonymous function is called, execute it. }); } }; In myFirstFunction, if I do return new callback(), then it works and executes the anonymous function, but that doesn't seem like the correct approach to me.
