 JavaScript Web Workers JavaScript was designed to run in a single-threaded environment, meaning multiple scripts cannot run at the same time.  But JavaScript runtime is not run in single thread. Let’s take big loop example if you run in the chrome and at the same time at Firefox you will encounter with a warning Unresponsive script. Here what, web workers  is a JavaScript API that allows you to run scripts in a separate thread from the main one. It can come in handy when you don’t want any hindrance in the execution of the main scripts. Web Workers allow for long-running scripts that are not interrupted by scripts that respond to clicks or other user interactions, and allows long tasks to be executed without yielding to keep the page responsive. When a script is executing inside a Web Worker it cannot access the web page's window object (window.document), which means that Web Workers don't have direct access to the web page and the DOM API. Although Web...

Overview Minifying JavaScript files is an optimization technique to reduce JavaScript payload and the main-thread blocking time. Minification can help  reduce JavaScript file sizes  by removing comments, white spaces, and redundant code, and in some cases, also makes the code more efficient by using shorter variable and function names. The  smaller  these JavaScript files are, the  faster  they are downloaded, parsed, and executed by the browser. How does minifying JavaScript affect page  performance? Whenever the browser loads a page, it needs to download, parse, and execute JavaScript files during the page load. Since this happens on the main-thread  by default, a higher JavaScript payload will block the main-thread for longer, extending your page load. Minification makes your code leaner and more compact by removing unnecessary elements, decreasing the file size, reducing the bandwidth consumed, and speeding up your overall page load ...

  S ome compilers have a precompile or preprocessor to process statements, that are not part of the computer programming language. The preprocessor is the first to look at the source code file and performs several preprocessing operations before it's compiled by the compiler. In computer languages such as C there is a phase of translation known as preprocessing. The amount and kind of processing done depends on the nature of the preprocessor. Some preprocessors are only capable of performing relatively simple textual substitutions and macro expansions, while others have the power of full-fledged programming languages. No Preprocessor specifically designed for JavaScript. Lexical (Language) preprocessors are flexible, which means, they are preprocessors with lexical analysis rules, that can be customized and can used with JavaScript. It is advisable to use preprocessors that have been designed for a language having a similar syntax as JavaScript. Let us now explore the Google ...
