get the first element of array in Go
Code snippet on how to get the first element of array in Go
if len(myArray) > 0 {
firstElement := myArray[0]
}
This code snippet retrieves the first element of a given array myArray
. First, we check if the length of the array is greater than 0, represented by len(myArray) > 0
. If the length is greater than 0, it means the array is not empty, and we can declare a variable named firstElement
that points to the element at the first position in the array myArray
, which is myArray[0]
. This variable firstElement
now points to the first element of the array myArray
.
