JavaScript is a computer language, built in the mid-90s. With this language, you can expect multi-domain jobs. But with time, people realized in spite of being a fan favorite, JavaScript is lagging when it comes to server-end jobs. That is why business houses never trusted this skilled programming language.
Then experts came up with a solution – TypeScript. You can say, it is a rip-off of JavaScript. However, there are some significant differences between them as well. So, today in this article, we will let you know how both these languages are distinct in spite of being related.
Similarities Between JavaScript and TypeScript
Now before we pinpoint the differences between the JavaScript and TypeScript programming languages. You must have some idea what these two languages are in the first place. It would be best if you also know the connections between the two before we unveil the differences.
First, let’s talk about JavaScript. We all know that it is a prevalent computer language used mainly in front-end development. On the other hand, TypeScript was created to better the performance of JavaScript. It offers server-side support that JavaScript lacks. In fact, it is one of the reasons TypeScript was built in the first place.
When it comes to the similarities, both the programming languages are open-source, which means the source codes are available for anyone to use. As TypeScript is written based on JavaScript, both languages understand their codes.
This means that if you write codes in JavaScript, you can convert them to TypeScript, and do the opposite as well. That’s not all, you can use JavaScript’s extensive library in TypeScript too.
Differences Between JavaScript and TypeScript
Now that we have an idea about how similar the two languages are, you will understand the distinction better. So far, we know that both languages are Object-Oriented.
However, as JavaScript is more of a Scripting language, its performance falters when we try to use it in enterprise solutions. But this is where TypeScript thrived. It is an ideal Object-Oriented language in spite of being a Scripting language.
When you write codes, sometimes you don’t need to define the variables. This feature is called Static Typing, something which is available in TypeScript but not in JavaScript. Another notable is Modules features. TypeScript has this feature, and JavaScript doesn’t.
The list goes on with JavaScript doesn’t have the Interface feature, whereas TypeScript has it. However, one of the most notable elements that JavaScript lack is the optional parameter functions. As of now, you might have guessed that TypeScript has it.
If we have done criticizing JavaScript, you will be happy to know that JavaScript has a vast set of program libraries that TypeScript doesn’t. So, it is a significant distinction as TypeScript only uses the contents not own them.
Conclusion
We can say that TypeScript is a modern-age JavaScript development language whereas JavaScript is a scripting language that helps you create interactive web pages.
