# Iterating Over Arrays

Arrays can potentially contain a large amount of related data, and sometimes, we want to access and modify data in bulk. An easier way to achieve this is by looping through an array to work with its elements collectively.

We can traverse the entire array using a `for` loop. The `len` function provides us with the length of the array, which we can use in the loop condition to specify the number of iterations:

index.go

In the code above, we employ a `for` loop to iterate `len(numbers)` times, where `len(numbers)` represents the length of the array. Within the loop, we utilize the variable `i` for indexing and accessing the elements.

The following code increments all odd numbers and squares all even numbers in an array:

index.go

What is the correct way of using a for loop to loop through an array called `myArr` ?
