JavaScript is one of the most popular scripting languages for building engaging and interactive frontends of web applications. There are around 1.9 billion websites in the world and JavaScript is used in over 95% of all those websites.
TypeScript is a javaScript-based scripting language that extends its functionality and intends to be more explicit in terms of what data to use. TypeScript came fourth on the Octoverse survey for most popular language over the year, where JavaScript rules on top.
Both languages have several differences. In a few instances, TypeScript has an advantage over JavaScript but most times JavaScript has the upper hand. Here are several differences between the two:
1. TypeScript is a statically typed scripting language whereas JavaScript is a dynamically typed scripting language.
2. TypeScript uses a compiler to compile code, which takes more time than JavaScript, which does not use a compiler
3. The learning curve in TypeScript is high and requires prior knowledge of JavaScript and other scripting languages.
4. JavaScript is older and has a large and strong community compared to TypeScript.
5. Apps built using TypesScript need to compile and transform in JavaScript to run on the browsers. Apps built using JavaScript run directly on the browsers.
6. TypeScript can highlight errors in the code during compilation, while JavaScript does so at runtime.
Deciding which one’s better out of JavaScript and TypeScript depends on Performance, Popularity, and Project Scale. The team at ashutec has come up with a guide to help you decide. Read more about which scripting language is better out of JavaScript and TypeScript.
