How to remove the first character of a string in Ruby

In this tutorial, we are going to learn about how to remove the first character of a given string in Ruby.

Consider, we have the following string:

str = "welcome"

Now, we want to remove the first character w from the above string.

Removing the first character

To remove the first character of a string in Ruby, we can use the built-in slice!() method by passing a character index.

Here is an example, that removes the first character w from the following string.

str = "welcome"

str.slice!(0)

puts str

Output:

"elcome"

Similarly, we can also use the subscript syntax [1..-1] to remove the first character of a string.

str = "welcome"

str = str[1..-1]

puts str

The above syntax extract the string from the index 1 to the last character index.
