What are the differences between jQuery and vanilla JavaScript?
jQuery is a library that simplifies DOM manipulation, while vanilla JavaScript is the core language. jQuery provides easier syntax and cross-browser compatibility.
Can you give me an example of how to select an element using both?
Sure! In jQuery, you would use $('.myClass')
, while in vanilla JavaScript, you would use document.querySelector('.myClass')
.
Is jQuery still relevant today?
While jQuery is still used in many projects, modern JavaScript (ES6+) has introduced features that reduce the need for it. Many developers now prefer vanilla JavaScript or frameworks like React.
What are the performance differences between the two?
Vanilla JavaScript generally performs better because it doesn't have the overhead of a library. However, for small tasks, the difference may be negligible.
