In Ruby, you can find the first element of an array using the first method. Here's an example:
fruits = ["apple", "banana", "orange"]
first_fruit = fruits.first
puts first_fruit # output: "apple"
In this example, we define an array of fruits and store it in the variable fruits. We then use the first method to retrieve the first element of the array and store it in the variable first_fruit. Finally, we output the value of first_fruit, which is "apple".
Alternatively, you can also use the index position of the first element (which is 0) to get the value. Here's another example:
fruits = ["apple", "banana", "orange"]
first_fruit = fruits[0]
puts first_fruit # output: "apple"
In this example, we again define an array of fruits and store it in the variable fruits. However, this time we use the index position [0] to retrieve the first element of the array and store it in the variable first_fruit. Finally, we output the value of first_fruit, which is again "apple".
