Basic Gruntfile.js after adding a configuration for the jshint task.

Gruntfile.js

// wrapper function
module.exports = function(grunt){
	// load all our Grunt plugins
	require('load-grunt-tasks')(grunt);

	grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        // task configuration goes here

        jshint: {
        	options: {
        		"node": true,
        		"esnext": true,
        		"curly": false,
        		"smarttabs": true,
        		"indent": 2,
        		"quotmark": "single"
        	},
        	all: ['Gruntfile.js', 'scripts/{,*/}*.js']
        }

    });

    // define the default task that executes when we run 'grunt' from inside the project
    grunt.registerTask('default', []);

};
