One could install jscs using command such as “npm install -g jscs”. You could also setup Javascript development environment using Dockers as detailed in this page. Once installed, all that is required to be done is following:
Following is a sample file, hello.js, created with a space after parenthesis:
console.log( "Hello World" );
Following is written in .jscsrc file:
{
"disallowSpacesInsideParentheses": true
}
Save both the files, hello.js and .jscsrc in the same folder. Following command could be used to execute the JSCS tool. In real world scenario, you could use Grunt to run jscs. The command below assumes that you have saved the formatting rules in a file saved as .jscsrc.
jscs -c .jscsrc ./
Once executed, following error will show up as there are spaced within parenthesis.
