TypeScript: How to install it & Exercises for Beginners | Learn TypeScript

In this video I present how to install TypeScript (and NodeJS) as well as ts-node on your machine. Then we use the REPL feature of ts-node to learn some simple things like operators and functions in TypeScript. This video covers four basic TypeScript exercises as to be found in my upcoming book on TypeScript. If you want to be informed about the book's release, just drop me a message or leave a comment. Operators covered: Addition, Subtraction, Multiplication, Division, Modulo, Exponentiation In the exercises we cover basics like simple mathematical calculations and the usage of simple functions like Math.cos and Math.acos for calculating the cosine and arcus cosine in TypeScript. In the last exercise we will implement a formula that converts degrees in celsius to degrees in fahrenheit. Then we will pack this logic into a function that we can call like any other function in TypeScript.
