JSFuck can be used to bypass detection of malicious code submitted on websites, e.g. in cross-site scripting (XSS) attacks. [10] Another potential use of JSFuck lies in code obfuscation. An optimized version of JSFuck has been used to encode jQuery, a JavaScript library, into a fully functional version written with just the six characters. [11]
Originally, Rhino compiled all JavaScript code to Java bytecode in generated Java class files. This produced the best performance, often beating the C++ implementation of JavaScript run with just-in-time compilation (JIT), but suffered from two faults. First, compiling time was long since generating bytecode and loading the generated classes ...
JScript.Encode is a method created by Microsoft used to encode both server and Client-side JavaScript or VB Script source code in order to protect the source code from copying. [1] JavaScript code is used for creating dynamic web content on many websites, with the source code easily viewable, so this was meant to protect the code.
The default type value for the script element in Internet Explorer is JavaScript, while JScript was its alias. [10] In an apparent transition from JScript to JavaScript, online, the Microsoft Edge [Legacy] Developer Guide refers to the Mozilla MDN web reference library as its definitive documentation. [11]
lolcode-java (A Java grammar / interpreter for the LOLCODE programming language) is a project also available [19] but it appears to not yet be compliant with the version 1.3 specification. A LOLCODE to JavaScript translator is also available. [20]
Ext JS is a composition of classes that has many capabilities. Some examples: an abstract layer for browsers (e.g. Ext.isArray that can be used as a replacement for Array.isArray)
push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack (wide index is constructed as indexbyte1 << 8 | indexbyte2) ldc2_w 14 0001 0100 2: indexbyte1, indexbyte2 → value
A Java class file is a file (with the .class filename extension) containing Java bytecode that can be executed on the Java Virtual Machine (JVM).A Java class file is usually produced by a Java compiler from Java programming language source files (.java files) containing Java classes (alternatively, other JVM languages can also be used to create class files).
