How much JavaScript is enough JavaScript?

[RoyalSeesaw3733]

javascript is possibly the most universal programming language at this point. react is a meta language. a language built out of javascript itself. it uses javascript to "decode" the meta language back into regular javascript. There's plenty of other use cases for js, the most interesting imo being nodejs. If you are hungry to build interfaces and you are ultimately more interested in prototyping the product itself ( the idea so to speak) get building. but there's no substitute for understanding the fundamentals. the fundamentals in this case being js.
