Why TypeScript over JavaScript
Purpose: understand when and why TypeScript is a better choice than plain JavaScript. Benefit: you can decide confidently for real projects.
Many beginners ask: why not just use JavaScript? ## JavaScript is great, but As projects grow: - files increase - logic becomes complex - bugs hide in corners JavaScript does not tell you: - what shape data should have - what a function expects - what it returns ## TypeScript gives answers With types, code becomes self-explanatory. ```ts function getUser(id: number): { name: string; age: number } { return { name: "Tom", age: 25 }; } ``` Anyone reading this knows: - id must be a number - result has name and age ## Benefits in real teams - fewer runtime crashes - easier refactoring - better IDE support - safer onboarding for new developers ## AI tools and TypeScript AI code tools work better when: - types describe intent - structures are clear - APIs are explicit That makes TypeScript very friendly for AI-assisted development. ## Remember - JavaScript is flexible - TypeScript is disciplined - discipline saves time in big projects
