 # Learn What matters in TypeScript lang(concepts which is maximum used codebase)



 

  

1. Type annotation 

 eg :- 

 let firstName : string = 45;

 let firstName : number = 45;

 let firstName : boolean = true;

 let firstName : undefined

   

  





 

  

2. Type Any & unknown both used in function (***parameter***)=>{...}

:Any = store any type of data without any type checking by the TypeScript compiler   

:unknown = best used when you don't know the type of data being typed. To add a type later

   

  





 

  

3.TypeScript function 

 function greet (value: number): string //compulsory// {

console.log("Hello"+ value)

}

greet(12:number) //compulsory//

  

  





 

  

4. Type Array in TypeScript

eg: 

const names : string [ ] = ["a", "b", "c", "d];

 

  





 

  

5. Type Object in TypeScript


interface CarProps {

  type: string

  model: string

  year: number

}

eg:  const car = {

  type: "Toyota",

  model: "Corolla",

  year: 2009

};
