JavaScript in computer science
Mastering algorithms is essential for working with JavaScript, especially when it comes to creating innovative products such as those based on artificial intelligence. An algorithm is a series of sequential instructions that allow actions or programs to be executed, and is central to the functioning of a program.
Some articles that will help you more effectively use algorithms in your JavaScript applications include:

JavaScript and programming paradigms
Programming paradigms (such as OOP, FP, and FRP) are fundamental principles of software creation. They represent different styles of generating code and giving instructions to machines, computers, and other devices. You can understand a programming paradigm as a path or a guide that streamlines web development by applying a certain structure and rules.
The following articles will show you how to apply some programming paradigms with JavaScript:

JavaScript and performance
JavaScript often triggers visual changes. Sometimes it does this directly through style manipulations, and sometimes through calculations that generate visual changes, such as searching or sorting data. Improperly timed or long-running JavaScript is a common cause of performance problems, and you should try to avoid this whenever possible.
