								## Description

								So far, you have only been checking if a pattern exists or not within a string. You can also extract the actual matches you found with the < code > .match()< / code >  method.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								To use the < code > .match()< / code >  method, apply the method on a string and pass in the regex inside the parentheses. Here's an example:
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								< blockquote > "Hello, World!".match(/Hello/);< br > // Returns ["Hello"]< br > let ourStr = "Regular expressions";< br > let ourRegex = /expressions/;< br > ourStr.match(ourRegex);< br > // Returns ["expressions"]< / blockquote >  
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								< / section >

								< section  id = 'instructions' >  
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								Apply the < code > .match()< / code >  method to extract the word < code > coding< / code > .
