I will disagree with Rishabh on this one, it\’s only when I started with JavaScript did I truly come to appreciate the design decisions that are made in any programming language.
JavaScript taught me a whole lot of semantic concepts. Be it the prototypal school of inheritance, or functional programming concepts like closures, functions as first class citizens, higher order functions.
Yes, JavaScript did have a bad reputation a while back, but let bygones be bygones. Investing sometime – emphasis on the fact that you need to invest time in learning the language, the design decisions and especially it\’s good parts will enrich your repertoire.
Today JavaScript is pervasive, node.js in the server, EcmaScript 5.1 in the browser, databases all were powered by this language. So, the investment is well worth the gains.
