Hello Friends 👋,

Welcome To Infinitbility! ❤️

In TypeScript, create array has some different syntax because typescript supports static typing.

i.e when we create an array we have first what we will store in the array-like string, number, object, etc.

Today, we will learn how to create an array and how to check array length in typescript.

Let’s start with the creation

Now, we are going to create an array of objects then we have to provide Array<object> before storing data in variables like the below example.

1let exampleArr: Array<Object> = [
2 { id: 1, name: 'infinitbility' },
3 { id: 2, name: 'notebility' },
4 { id: 2, name: 'repairbility' },

To check the length of the array we have the .length option to know the length of the array.

To find the length of exampleArr we have to write exampleArr.length and it will return 3.

1let exampleArr: Array<Object> = [
2 { id: 1, name: 'infinitbility' },
3 { id: 2, name: 'notebility' },
4 { id: 2, name: 'repairbility' },
