JSON vs. JavaScript vs. RuboCop vs. Velocity.js 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.

RuboCop is a Ruby code style checker (linter) and formatter based on the community-driven Ruby Style Guide. RuboCop is extremely flexible and most aspects of its behavior can be tweaked via various configuration options. In practice RuboCop supports pretty much every (reasonably popular) coding style that you can think of. Apart from reporting problems in your code, RuboCop can also automatically fix some of the problems for you. RuboCop packs a lot of features on top of what you’d normally expect from a linter. Works with every major Ruby implementation. Auto-correction of many of the code offenses it detects. Robust code formatting capabilities. Multiple result formatters for both interactive use and for feeding data into other tools. Ability to have different configuration for different parts of your codebase. Ability to disable certain cops only for specific files or parts of files.
