What's the Difference Between jQuery Selector and DOM querySelectorAll()?
What is the Difference Between jQuery Selector and DOM querySelectorAll()?
As of , all major browsers have
querySelectorAll() method. For example:
let myList = document.querySelectorAll("span.x, span.y");
So, why use jQuery?
• Internet Explorer 8 or before does not fully support
querySelectorAll(css_selector) [see CSS Selector Syntax]
• The array-like object returned by
$(…) is more powerful than the array-like object (a NodeList) returned by
querySelectorAll(…). [see JS: Array-Like Object], because:
jQuery selector returns a special jQuery object. This object, has methods that work with html elements. All of them work on the result, by simply using the dot syntax of property access (aka chaining), and they apply to each element without needing to use map or for loop.
array methods on them directly, such as
[see JS: Array-Like Object to Array]
[see DOM: NodeList vs HTMLCollection]
The disadvantage of using jQuery is speed and bloat.
