Setup NODE in Chromebook

I have a Chromebook pc and I installed Linux but I could not install Node following the chapter ’ Setting Up Node Locally’. I googled a lot and tried all the possible workaround but none of them worked. I also problem understanding what is the correct Node version I should install.
But anyway is that really necessary for Coding in the Front-end path? Can’t I just use the browser instead of Node?

Many thanks in advance
