JavaScript: The Most Popular Programming Language

According to the 2023 Stack Overflow Developer Survey, JavaScript has maintained its position as the most widely used programming language for 11 consecutive years, with 66% of developers using it extensively. If you’re aspiring to become a web developer—whether in front-end, back-end, or full-stack development—JavaScript is one of the most valuable programming languages to master. A practical way to start learning is by working on beginner-friendly JavaScript projects.

Understanding Vanilla JavaScript

Vanilla JavaScript, often referred to as plain JavaScript (without any frameworks or libraries), is a cornerstone of coding and web development. Most websites are built using a combination of HTML, CSS, vanilla JavaScript, and API integrations. Familiarizing yourself with JavaScript fundamentals is essential, and the best way to solidify your knowledge is by building hands-on JavaScript practice projects.
