How to remove the first element of an array in Ruby
In this post we will give you information about How to remove the first element of an array in Ruby. Hear we will give you detail about How to remove the first element of an array in RubyAnd how to use it also give you demo for it if it is necessary.
we are going to learn about how to remove the first element of a given array in Ruby.
Consider, we have the following array:
prices = [10, 20, 30, 40]
Now, we want to remove the first element 10 from the above array.
Removing the first element
To remove the first element of an array, we can use the built-in shift method in Ruby
Here is an example, that removes the first element 10 from the following array.
prices = [10, 20, 30, 40]prices.shiftputs prices
Output:
[20, 30, 40]
Note: The shift method modifies the original array.
If you don’t want to modify the original array, you can use the drop() method in Ruby.
prices = [10, 20, 30, 40]adjusted_prices = prices.drop(1)puts adjusted_prices
Output:
[20, 30, 40]
In the above example, we have passed 1 as an argument to the drop() method. so it creates a new array by removing the first element from the prices array.
