π§ What is JavaScript Deobfuscation?
JavaScript Deobfuscation is the process of reversing obfuscation, transforming hard-to-read or compressed code back into a human-readable format.
π Example:
Obfuscated Code:
javascriptCopyEditeval(function(p,a,c,k,e,d){e=function(c){return c.toString(36)};...})
Deobfuscated Output:
javascriptCopyEditfunction sayHello() {
alert("Hello, world!");
}
sayHello();
