Why Typescript

• Brings Type System into Javascript
• Helps you spot errors in your code as you type
• Less debugging and testing time needed
• Providing types is a form of documenting code
• Easy to learn from Javascript developers and not only
• Provides rich configuration along with non-JS features like interfaces

Summarising the above:

1. Less errors found in production
2. Faster delivery
3. Easier code management
4. Increased code quality & team performance
