![]() ![]() But there are really amazing examples of obfuscation, for example, JSFuck can display any JavaScript code with just the following six characters ()!+įor example, the following code is workable JavaScript code: Often during obfuscation, the code turns into a meaningless set of functions and lines that cannot be understood, but which ultimately do exactly the same thing as the source code. As a side effect, this code is really hard to figure out. This is called code minify and is used not only to obfuscate, but to speed up script downloads. Obfuscation is especially relevant for JavaScript, because, unlike, for example, PHP that runs on the web server, JavaScript is loaded into the browser and each user can have access to scripts. ![]() That is, it is JavaScript, PHP, obfuscation can be used for HTML (although it is a markup language, not a programming language), CSS and others, programs on which do not compile, but run in plain text. Obfuscation is used for source code in interpreted (rather than compiled) programming languages. Obfuscation is source code modification as a result it becomes difficult to read and understand, but so that its functionality does not change. ![]()
