  Name resolution order in JavaScript

To understand what value a variable has in JavaScript, we need to understand some concepts such as scope and name resolution order. JavaScript has two scopes; one is program level and the other one is function level. Unlike in C,C++ or Java, JavaScript has no block level scope. So a variable defined in a if block will still be available outside. For example, the below example: var foo = 1; function bar() { if (true) { var foo = 10; } alert(foo); } bar(); The alert will display 10 since the ...

  ARE YOU LIKE ME? OR DO YOU HAVE DISCIPLINE?

If you are anything like me, you've started more things than you have finished. We're innately curious about the things around us and inspired when we come across people who have mastered their trade. We see people create cool and beautiful things and think, "Man, that looks easy, if I put in a little time I can do that in no time." What follows is a few days or weeks of focused and dedicated learning. During this time we make some progress, but not much. In fact, the progress that we do ma...

So let's say you're an awesome web developer making an awesome web app. One day, you add a link in the web app that has an event handler instead of an href.

You are happy.The next day, QA informs you that the link cannot be tabbed to. Confused, you do some research and find a solution to the problem: Sim...

This is as good a place as any, and hopefully it will be useful to others.I needed to make an Ajax call, so I turned to my good friend XMLHttpRequest. One wrinkle was that I needed to pass in a parameter to it… so I tried:var test = "bar"; req = new XMLHttpRequest(); req.open("GET", myURL, true); req.foo = test; req.onreadystatech...
