Demystifying JavaScript Closures, Callbacks and IIFEs

Demystifying JavaScript Closures, Callbacks and IIFEs

This article will explore in-depth three crucial concepts in modern JavaScript development: closures, callback functions, and immediate execution function expressions (IIFE). We have learned in detail about variable scope and enhancement, and now let's complete our exploration journey. Core points JavaScript closures are functions that can access their parent scope variables. Even if the parent function has been executed, the closure can still remember and manipulate these variables. Callback functions are functions passed as parameters to other functions, which are then executed within external functions, thus providing a way to delay execution or maintain the order of asynchronous operations. Execute function expressions (IIFE) are functions that are executed immediately after definition to protect the scope of variables and prevent

How to Build Your Own CSS Preprocessor With PostCSS

How to Build Your Own CSS Preprocessor With PostCSS

Key Points PostCSS allows developers to build their own CSS preprocessors, providing greater flexibility and control over other preprocessors such as Sass, LESS or Stylus. It uses JavaScript plugin to manipulate styles and is able to add preprocessor-like features such as variables, mixins, and nesting. The advantages of PostCSS include modularity, lightweight builds, instant implementation of new features, and the ability to enforce development strategies. It is also faster than traditional preprocessors. However, it also has some disadvantages, such as the increased complexity of the build process, different syntax, and the requirements for effective CSS. While PostCSS has great potential, it may not be suitable for all projects. for
