Ajax and json

Question

is it necessary to learn ajax and json for web development?

Answer 1

Ajax is cool to know, because you communicate the client to the server through Ajax. You can search something in a database for example without having to refresh or go to another page.

Json as its name states (JavaScript object notation) is a syntax to build objects in JavaScript and also is used when storing data. It kinda replaced XML because you write less and have cleaner syntax.

It's not mandatory to learn them, but they might come in handy. Json for readability, Ajax for functionality.

Answer 2

Good to know, but not necessary, especially if you plan on focusing on front end instead.

Answer 3

Yes
