TypeScript vs. JavaScript: Making the Right Choice

When diving into the world of web development, one often encounters the age-old debate: TypeScript or JavaScript? Both have their merits, and the best choice largely depends on your unique needs and preferences. However, understanding their core differences and use-cases can guide your decision-making process.


A Personalized Approach to the Debate

Choosing between TypeScript and JavaScript isn’t as straightforward as looking at an online comparison table. Adam Abrams, the Director of Architecture at Optimove, emphasizes the importance of evaluating both languages based on your organization’s specific requirements. For instance, while Optimove extensively uses JavaScript for both front-end and back-end tasks, it also incorporates other technologies like .NET and Java. The team’s familiarity with type-oriented languages prompted their choice to standardize on TypeScript for most of their services.


Tackling the Challenges

Andrew Pierno from Veritone highlights some challenges when picking a side. According to him, JavaScript’s adaptability can sometimes lead to complications. Despite its versatility, spanning from web apps to blockchain solutions, JavaScript’s eccentricities can prove daunting. On the flip side, TypeScript provides the comfort of a strongly-typed language, bridging the gap for developers transitioning from other languages. It offers an additional layer of protection, catching bugs that might slip through in vanilla JavaScript.


Weighing the Differences

When debating TypeScript vs. JavaScript, the conversion between the two should be a key consideration. Transitioning from JavaScript to TypeScript might prove labor-intensive, especially if your team is more familiar with the former. Jacob Ansari from Schellman advises against migrating for security reasons unless the benefits outweigh the costs, such as when a new team prefers the new language.


The Verdict from Experts

Carl Saunders, a co-founder and developer at Raven Code Limited, vouches for TypeScript. In his view, its ability to transcompile down to JavaScript gives it an edge. Modern development tools like Visual Studio Code and WebStorm seamlessly integrate with TypeScript. The IntelliSense support, early adoption of ECMAScript features, and integration into continuous integration pipelines make TypeScript an appealing choice for many.


Conclusion: Which Should You Opt for?

Your decision between TypeScript and JavaScript should factor in your current environment. If you’re already utilizing one, assess the benefits and drawbacks before making a switch. However, for those starting anew, familiarizing oneself with the above insights and dabbling in both languages will help make an informed choice tailored to your organization’s needs.
