![]() In Swift on the other hand, you have nil and it can only be assigned to null-able or optional variables (as shown below). Nothing or null is an essential ingredient in dynamic typed languages including JavaScript), but as I mentioned earlier, Swift is a static typed language, so you cannot have Mr. The same applies to constants, except the fact that you can declare them only once. ![]() For example in Swift, if you want to separate the definition and declaration, it would have to be like this: Since JavaScript is completely a dynamically typed language, so all the variables used in it are either strings, functions or objects, while in Swift, the language is strictly static type based, so you have to mention the types explicitly. Both JavaScript and Swift use the var expression to define a new variable with a value (as shown below).Īdditionally in Swift, constants can be defined as:Īnd therein lies the first difference. If you compare them syntactically, there are some subtle differences. And yes the semicolons are not-required in both languages □ Here’s how we write Hello World in JavaScriptĪs you can see from the code snippets above, they are more or less the same. Let’s look at the below Hello World program as an example. In terms of syntax though there are some minor differences between JavaScript and Swift but not much. The reason behind this is like most other programming platforms that use JavaScript as their base – like Unity for example – Swift is also based on JavaScript.įACT: JavaScript is the top and trending language on GitHub, with almost 30% of all repositories present there in 2015, and it’s still on the rise. The suspense was over soon though when Apple unveiled its new language called Swift that is different in form, but similar in essence to Objective-C.Īfter getting an initial hands-on with Swiftly, as someone who has worked on JavaScript, Python & C#, my first impressions were that it’s a lot like JavaScript and, in few areas, like Python & C#. This was a major change which caused a lot of excitement in the programming world, since everyone wanted to know what this new programming language would be like. So in the first blog from the series, let’s look at the basic similarities between these two languages.Īlthough most programming languages have changed over time, Apple’s Objective-C language has remained more or less constant, that is until recently, when Apple announced a brand new programming language for its devices. In this first post, I’m going to look at the basic syntactical comparison between JavaScript and Swift and in future posts I’ll explore both these languages in more detail. This is a series of blogs that will present a comparative analysis of JavaScript and Apple’s Swift programming language.
