Finding the Location of a String in Ruby

To find the location of a string in Ruby, you can use the index method. The index method returns the position of the first occurrence of a substring within a string. Here's how you can use it:

string = "Hello, world!"
substring = "world"

location = string.index(substring)
puts location

In this example, the index method is called on the string variable with the substring as an argument. The method returns the index of the first occurrence of the substring within the string. The result is then printed to the console.

The output of the above code will be:


This means that the substring "world" starts at index 7 in the string "Hello, world!".

Please note that the index method returns nil if the substring is not found in the string.
