JavaScript is widely used in designing websites. While writing JavaScript code, we use several white spaces, comments, and tabs for readability and maintenance of code. But the use of a lot of white spaces and tabs in JavaScript causes the file size to increase. As the file size increases, it increases page load times. Hence most of the professional websites use compressed JavaScripts for fast loading. Compression is mostly squeezing white spaces and newline characters. Once JavaScript is compressed, it can be decompressed by adding enough white space and newline characters, which makes it readable. Usually, obfuscated code also can be made readable by inserting white space and newlines. This recipe is an attempt to hack similar capabilities in the shell.
