How to find sub-string between the two words using jQuery ?

Given a string containing words and the task is to find substring between two given words using jQuery. There are two methods to solve this problem which are discussed below: Using match() method: It searches a string for a match against any regular expression and if the match is found then it returns the match string as an array. Syntax:

string.match( regexp )

Approach:

Get the string from the HTML element.
Provide the regular expression in the format like "starting_word(.*)ending_word".
The substring between the starting_word and ending_word(exclusivly) will be extracted.

Example:
