- Regular Expression with
includes() method is the most straightforward way to check if a string contains a substring. It returns
true if the substring is found and
indexOf() method returns the index at which the substring is found in the string, or
-1 if it's not found. It's a versatile method that can also be used to determine the presence of a substring.
This method executes a search for a match between a regular expression and a string. It returns the index of the match, or
-1 if not found. This can be useful for more complex pattern matching.
match() is used to retrieve the matches when a string is matched against a regular expression. It returns an array of matches or
null if no match is found.
Regular Expression with
Regular expressions are powerful for pattern matching and can be used with the
test() method to check for the presence of a substring.
These methods are used to check if a string starts or ends with a specific substring.
Each method has its use cases and benefits. For instance,
indexOf() are straightforward for simple substring checks, while regular expressions provide more flexibility and power in pattern matching. Choose the method that best fits the specific needs of your task. Remember, the right tool for the job can make your code more efficient and easier to understand.
