Running grunt in Command Prompt gives ERROR:

Loading "gruntfile.js" tasks...ERROR >> SyntaxError: Unexpected token Warning: Task "default" not found. Use --force to continue.

I don't know where i have gone wrong..Any Help is Appreciated!

You have typo in your gruntfile.

Change

// ... config before
copy: {
    main: {
        files: []
            {expand: true, cwd: 'source/', src: ['**'], dest: 'dest/'}
        ],
    },
},
// ... config after

To:

// ... config before
copy: {
    main: {
        files: [ //removed array close
            {expand: true, cwd: 'source/', src: ['**'], dest: 'dest/'}
        ]
    }
},
// ... config after
