In TypeScript, like JavaScript,arrays are homogenous collections of values. We can define an array in the following ways. First, we can declare and initialize the array in the same line: letarray:number[]=[1,2,3];letarray:Array<number>=[1,2,3];letarray:number[]=newArray(1,2,3); ...

TypeScript allows us to sort the objects in the array. Example: varnumArray:{num:number;}[]=[{num:7},{num:9},{num:3},{num:6},{num:1}];numArray.sort(function(x,y){if(x.num>y.num){return1;}if(x.num<y.num){return-1;}return0;});console.log('The sorted array of objects...

Due to the nature of TypeScript, these element types are known at the point of initialization. With tuples, we can define the data type that can be stored in every position in an array. What are tuples? Tuples are like advanced arrays with extra features that ensure type safety, ...
