 ## Other Common String Methods
 
 - **The `indexOf` Method**: This method is used to search for a substring within a string. If the substring is found, `indexOf` returns the index (or position) of the first occurrence of that substring. If the substring is not found, `indexOf` returns -1, which indicates that the search was unsuccessful.
-- **The `includes()` Method**: This method is used to check if a string contains a specific substring. If the substring is found within the string, the method returns true otherwise, it returns false. 
+- **The `includes()` Method**: This method is used to check if a string contains a specific substring. If the substring is found within the string, the method returns true. Otherwise, it returns false. 
 - **The `slice()` Method**: This method extracts a portion of a string and returns a new string, without modifying the original string. It takes two parameters: the starting index and the optional ending index. 
 - **The `toUpperCase()` Method**: This method converts all the characters to uppercase letters and returns a new string with all uppercase characters. 
 - **The `toLowerCase()` Method**: This method converts all characters in a string to lowercase.
