Ways to Iterate JavaScript Arrays

The objective of this article is to understand different possible ways to loop through JavaScript Arrays.

Declare array

const arr=[‘kiwi’,’dragon’,’orange’,’apple’,’pomegranate’];
const sal=[2200,5000,2100,1500,3700,4300];
let sal_incr=[]

for() loop

for loop is an iterative statement, it checks for some conditions and then executes a block of code repeatedly as long as those conditions are met.

console.log(“Arrays for loop”)

for (let i=0;i<arr.length;i++){
    console.log(arr[i])
}

Output:

for..in loop

for…in loop is an easier way to loop through arrays as it gives us the key which …
