What is TypeScript
Features of Typescript
You can convert any valid .js file to .ts by renaming the file and can be compiled with other TypeScript files.
Benefits of TypeScript
The TypeScript transpiler provides the error-checking feature. TypeScript will compile the code and generate compilation errors, if it finds some sort of syntax errors. This helps to highlight errors before the script is run.
TypeScript supports Object Oriented Programming concepts like classes, interfaces, inheritance, etc.
TypeScript comes with an optional static typin.
Components of TypeScript
