#SHOULD I LEARN JAVA OR JAVASCRIPT SOFTWARE#

Long story short: Dynamically-typed languages do not require you to declare data types. Let result = ' Javascript is sometimes a bit daft ' // result is type string if ( result = ' Javascript is sometimes a bit daft ' ) return result // 10 - all compiles OK (?!)Ĭlearly in a statically typed language such as Java this would throw a bunch of errors.

If we look at an example, we will quickly grasp what a “type” is!

While this may seem like a fairly innocuous concept the idea of explicitly defining a type is (in my opinion) one of the biggest differences between Java and Javascript. The list is by no means exhaustive, and I imagine some Java purists will choke as they read through, but I’m hoping that the lessons I learned might hopefully let someone else make the jump to being a “full stack” developer a little easier than I did! Start with “type”-ing in Javascript I’ve put together a list of a few bits and pieces of advice that helped me bridge the gap between knowing Javascript and beginning to learn Java. I’m by no means a Java wizard yet, but I’m making good progress and can now contribute effectively to the whole stack that our team is working on. I’ve been looking at (and contributing to) the Java codebase now for just over six weeks on the current application I’m building. I resolved to fix this and decided to learn as much Java as I needed to start understanding the server codebase, and to contribute (slightly!) to the changes needed as the application we were building evolved. It would slow me down and would also slow down the person who I asked to make the changes for me. This meant I ended up waiting around for a while or trying to switch focus and work on something else as I waited for the server changes to be done. I had an extensive depth of knowledge for anything Angular, but if the task involved going into the server side to do any work at all I was immediately stumped and had to ask for help. Our application had an Angular front end and a Java server connected to a database, which was a fairly standard application setup. About 3 months ago I was working exclusively in the front-end stack, and in that, more or less entirely in Javascript. This means if you’re a developer who has a very deep knowledge of Javascript and have a multitude of tech stacks you can write in (Angular, React, etc.) but the idea of booting up a Tomcat server in Java terrifies you then you might quickly find yourself struggling to fit into and contribute a comparable amount of value to a team that requires “full stack” developers. What it means in a nutshell is that as the universe of coding evolves, and as the lines blur between “Server work does the heavy lifting” and “front end shows the nice stuff” the demand for developers who have multiple facets of knowledge is growing. That’s a fairly typical request, from either internal development teams advertising for new starters, or from clients to consultants when they want to onboard a new member of a team. Some knowledge of Java is also useful.”, as a real life example.

That is, most software roles now are looking to fill the position with someone who has “Extensive knowledge of Javascript, specifically React, Redux, and experience in TDD. There is a real demand in the software industry for specialists who don’t specialise. Why should I even bother, Javascript is the best language ever?
