Why do we need to use join() method? please explain:)
Hey Karem,
According to my approach, navbarClasses is an array of 2 strings. So, to make a single string from those, join() will make it happen.
navbarClasses
console.log( ['navbar','scrolled'].join(" ") ) // "navbar scrolled"
Another approach is to use Ternary operator like this:
className={scrolled ? 'navbar scrolled' : 'navbar'}
I hope I've cleared it out ;)
Thanks Rohit! Great explanation :)
