Someone could tell me, during his programming career, how he knew he would need to learn how to use AJAX, what was the purpose etc.?
I’ve been trying to figure out AJAX from W3schools for hours, but I can only figure it out when I understand what I’m dealing with. I have always tried to take a different route so as not to use AJAX, but it seems inevitable to me to go on without knowing it. And I also can’t just copy from the Internet copy to my work and work without knowing what it is and what it’s going to do.
I learned why I wanted to create scripts to automate some actions on sites (this at the time of Orkut), but anyway. What’s the difficulty? the concept is simple, you access a URL in "background", without the user seeing, and receive the content of the page in a variable. More complicated is knowing how to work with this content, if you want it to dynamically modify something on the screen, but in this case, the problem is not AJAX itself.

Only in this small comment I was able to 'access the doors' in my reasoning, and notice the use of AJAX. Thanks user5978
