Migrating from jQuery to Modern Vanilla JS
Replace legacy jQuery calls with modern standard browser APIs: document.querySelector, classList, and fetch().
The Modern Vanilla JavaScript Equivalent Table
Modern browsers natively provide everything jQuery was originally invented for, with zero download weight:
| jQuery Syntax | Modern Standard Vanilla JavaScript |
|---|---|
| $("#my-id") | document.getElementById("my-id") |
| $(".btn") | document.querySelectorAll(".btn") |
| $(elem).addClass("active") | elem.classList.add("active") |
| $(elem).on("click", fn) | elem.addEventListener("click", fn) |
| $.get(url, fn) | const data = await (await fetch(url)).json() |
