Frontend Engineering and Javascript

User interfaces are becoming increasingly complex, especially on the web. Frontend engineering questions are now fair game for all software engineers, as your user experience will be compromised until you've mastered this area.

Once you have a solid grasp of the fundamentals of JavaScript, such as variables, data types, functions, loops, and DOM manipulation, there are a number of powerful intermediate language features and concepts that are important for front-end developers to understand.

These concepts will allow you to write more concise, performant, and scalable JavaScript code in your applications and modules. Mastering these ideas will level up your ability to tackle complex JavaScript projects and frameworks.
