Most of us are familiar with jquery and probably quite a few of us are familiar with the Chrome console's
$$ shorthands for query selectors. I recently figured out a way to replicate these shorthands in my code, using
Function.prototype.bind(). Here's how to do it, just make sure you don't mix them up with jquery if you are still using it:
const $ = document.querySelector.bind(document); const $$ = document.querySelectorAll.bind(document); const mainContent = $('.main-content'); const externalLinks = $$('a[target="_blank"]');
A collection of quick tips and tricks to level up your coding skills one step at a time.
Creates a counter with the specified range, step and duration for the specified selector.
Creates an element from a string (without appending it to the document). If the given string contains multiple elements, only the first one will be returned.
Creates an object containing the parameters of the current URL.
