+excerpt: Ever wanted to create your own jquery-like query selector shorthand? Here's how!
+---
+
+Most of us are familiar with jquery and probably quite a few of us are familiar with the Chrome console's `$` and `$$` shorthands for query selectors. I recently figured out a way to replicate these shorthands in my code, using `Document.querySelector()`, `Document.querySelectorAll()` and `Function.prototype.bind()`. Here's how to do it, just make sure you don't mix them up with jquery if you are still using it:
+
+```js
+const $ = document.querySelector.bind(document);
+const $$ = document.querySelectorAll.bind(document);
+
+const mainContent = $('.main-content');
+const externalLinks = $('a[target="_blank"]');
+```
