JSON vs. JavaScript vs. ProGuard vs. Roy Comparison Chart

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.

ProGuard: Open Source Optimizer for Java and Kotlin. ProGuard is the most popular optimizer for Java bytecode. ProGuard also provides minimal protection against reverse engineering by obfuscating the names of classes, fields and methods. ProGuard reduces the download and startup time of Android applications and improves their performance on mobile devices. ProGuard obfuscates Java applications and pre-verifies the processed code for Java Micro Edition and for Java 6 and higher. ProGuard optimizes and obfuscates Java applications for cell phones, Blu-ray players, set-top boxes and other constrained devices. ProGuard fully supports Java and Kotlin applications, enabling developers to take full advantage of these languages’ features without sacrificing performance or security. ProGuard is a command-line tool with an optional graphical user interface. ProGuard is fast: It processes small Android applications and entire runtime libraries in seconds.
