Introduction to TypeScript, Singapore

We can host this training at your preferred location. Contact us!

JavaScript is a powerful language that is ubiquitous in the Web. However, its dynamic and interpreted nature can lead to problems at scale, problems that are mitigated in other languages by compilation and static typing. TypeScript brings these benefits to the JavaScript universe.

TypeScript is a type safe superset of JavaScript that allows us to write clean, simple code that runs anywhere JavaScript does. Unlike other languages that can transpile to JavaScript, the interop between JavaScript and TypeScript is a primary engineering concern. As a superset, all JavaScript skills and legacy code are readily reusable. Type safety brings many benefits, including catching bugs at compile time instead of run time, advanced static analysis tooling, powerful refactorings, better IDE experience etc.

Delegates must be proficient JavaScript developers. However, the delivery time can be extended if have no prior knowledge of JavaScript.
