For in TypeScript

In TypeScript, for loop is used to iterate through a collection of elements like arrays, objects or strings. It allows us to execute a block of code repeatedly until the specified condition is true.

The syntax for using for loop in TypeScript is:

for(initialization; condition; increment/decrement) {
    // code to be executed
}

Let's understand the above syntax using an example to iterate through an array:

let arr: number[] = [10, 20, 30, 40, 50];
for(let i=0; i
    console.log(arr[i]);

}

In the above example, we have initialized i as 0, condition as i

The output of the above loop is:

10
20
30
40
50

Similarly, you can use for loop on other collection types like objects or strings and can perform the desired operations.
