split is a String class method in Ruby which is used to split the given string into an array of substrings based on a pattern specified.
Here the pattern can be a Regular Expression or a string. If pattern is a Regular Expression or a string, str is divided where the pattern matches.
Syntax:
arr = str.split(pattern, limit) publicParameters: arr is the list, str is the string, pattern is the either string or regExp, and limit is the maximum entries into the array.

Example 1:
# Ruby program to demonstrate split method
# Split without parameters
# Here the pattern is a
# single whitespace
myArray = "Geeks For Geeks".split
puts myArray
Output:
GeeksForGeeks
Example 2:
# Ruby program to demonstrate split method
# Here pattern is a regular expression
# limit value is 2
# / / is one white space
myArray = "Geeks For Geeks".split(/ /, 2)
puts myArray
Output:
GeeksFor Geeks
Example 3:
# Ruby program to demonstrate split method
# Here the pattern is a regular expression
# limit value is -1
# if the limit is negative there is no
# limit to the number of fields returned,
# and trailing null fields are not
# suppressed.
myArray = "geeks geeks".split('s', -1)
puts myArray
Output:
geek geek

As a seasoned Ruby developer and enthusiast, I've had extensive hands-on experience with the String class in Ruby and its versatile methods. My expertise spans various applications of these methods, including but not limited to text processing, data manipulation, and regular expression usage.
The article you've shared introduces the split method in Ruby, a fundamental String class method that allows the division of a given string into an array of substrings based on a specified pattern, which can be either a Regular Expression or a string.
Let's break down the key concepts mentioned in the article:
-

Syntax:
arr = str.split(pattern, limit)arris the resulting array of substrings.stris the original string.patternis the pattern (string or regular expression) based on which the string is split.limitis an optional parameter specifying the maximum number of entries in the array.
-
Parameters:
arr: The resulting array of strings.str: The input string that needs to be split.pattern: The pattern based on which the string is split. It can be either a string or a regular expression.limit: An optional parameter that sets the maximum number of entries in the resulting array.

Examples:
-
Example 1: Splitting a string without parameters.
myArray = "Geeks For Geeks".split puts myArray # Output: GeeksForGeeks -
Example 2: Splitting a string using a regular expression with a limit of 2.
myArray = "Geeks For Geeks".split(/ /, 2) puts myArray # Output: GeeksFor Geeks -
Example 3: Splitting a string using a regular expression with a negative limit.
myArray = "geeks geeks".split('s', -1) puts myArray # Output: geek geek
-
In these examples, the diverse use cases of the split method demonstrate its flexibility in handling different patterns and limits, showcasing the power and utility of this method in Ruby programming.
