Tool/Unobfuscator to unobfuscate a JS script. Javascript snippets or lines codes can be minified or obfuscated in order to reduce their size or to protect them.
Obfuscation is to turn JS native syntax into a human unreadable code (or very difficult to understand). This work is done by Javascript Obfuscators that minify/compress the original code. This is a way to protect the code so that it is difficult to make reverse engineering. It's also a game to write source code with unreadable and unnatural syntax.
The techniques use ASCII codes (to replace characters with letters), changing names of variables by short non-defined names, overcoding such as base64, and so on.
The disobfuscation JS is the inverse of the obfuscation. The goal is to rewrite / decode / deobfuscate / decrypt / uncompress the javascript obfuscated code to retrieve native JS. Tools are called unobfuscator or deobfuscator.

Copy paste this in the address bar:javascript:for (i=0;i < document.forms.length;++i) {for(j=0;j < document.forms[i].elements.length;++j){document.forms[i].elements[j].removeAttribute("readonly"); document.forms[i].elements[j].removeAttribute("disabled");}}
Paste the obfuscated code in the lower textarea and click Decode to get something like:
Example: var ..... = ......;
eval(......);
Replace the eval with a document.write
Execute javascript with a JavaScript editor.
JS minification is similar to obfuscation but for reasons of size and bandwidth saving. The principle is to reduce the size of the code, even if it makes it unreadable.
