Style Checker and Analyzer

Standard Js

Installation npm install standard --global in comand line interface to install globally npm install standard --save-dev in command line interface to install locally

Running Standard Js go to root of project and type standard if StandardJs is installed globally go to root of project and type npx standard if StandardJs is installed locally Instead of installing it using npm, you can also use the extension available on VS Code

IDE and Code Fomatter

• IDE and Style Checker: VSCode

• Code Style Formatter: Beautify

• Code Syntax Checker : Eslint for Vscode plugin.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.
