TypeScript is a programming language developed by Microsoft that builds on JavaScript by adding static typing and other development features. Think of it as JavaScript with an extra safety net, it helps developers catch potential errors before their code runs.
Unlike JavaScript, TypeScript allows you to define the type of data a variable, function, or object should contain. This can make large applications easier to maintain, especially when multiple developers are working on the same project.
Why Should You Use TypeScript?
One of the biggest advantages of TypeScript is improved code reliability. Your editor can detect many mistakes while you're writing code, saving you from discovering them later in the browser.
TypeScript also provides better autocomplete, clearer documentation, and easier refactoring. It works especially well with modern frameworks such as React, Next.js, and Node.js.
