I'm planning to learn JavaScript for web development, but I'm wondering whether it's still a worthwhile investment in 2026. Since AI tools can generate code from simple prompts, do developers still need to understand JavaScript and programming fundamentals? What are the main reasons people continue learning to code, and how important is JavaScript knowledge when working alongside AI?

JavaScript remains widely used for web development, so it’s a practical language to learn. It also gives you a foundation for TypeScript and popular tools such as React, Angular, and Vue. You don’t need to memorize every detail, but you should understand the fundamentals well enough to work effectively with AI-generated code.
Yes, especially if you want to work with JavaScript professionally. AI can generate code, but you still need to understand the language to review it, debug problems, make architectural decisions, and spot edge cases. The valuable skill isn’t just typing syntax—it’s knowing what the software should do and whether the generated solution is reliable.
