Get first name

Your Task 📚:

Create a function called getFirstNames where it takes a nested array of names and returns just the first name of each array

Examples 😃:

getFirstNames([["Ahmed","Aisha","Amina"],["Jaamac","Khadijah","Layla"],["Mohamed","Ali"]]) ➞ ["Ahmed","Jaamac","Mohamed"]

Good Luck 😀
