HI,

I'm just asking. Is it a powerful to build for interface website with CSS/Sass, Javascript only? is it good and fast with Bootstrap, Jquery?

Thanks Advanced,

Thank you for responding, Brendan. I meant load time in the browser for the user.

Hi Ali,

I had to learn jQuery in another bootcamp because it is really helpful with DOM manipulation. I've heard that React and Redux eventually replace the need for jQuery, and you may have noticed that Google Chrome has added a few things to its browser API so that you can use querySelector() without jQuery, among other features:

However, learning jQuery also helps you deal with legacy code, so that when you're dealing with code bases that haven't been built in the last few years you can understand and work with them.

I have put more emphasis on learning Flexbox and Grid in vanilla CSS, but I don't see why you wouldn't want to learn Bootstrap 4 as well.

Best,

Matt

If you're using the cdn, for either jQuery or Bootstrap, you can benefit from having it cached already in the user's browser. You can also do a custom build of Bootstrap to take only the pieces you want. JQuery isn't really necessary unless you're trying to target pretty old browsers. SCSS doesn't affect load time because it's transpiled into CSS before it gets to the browser. Overall, you're going to be fine building a website with jQuery and Bootstrap, usually it's things like images that make websites slow.
