								Using the hyphen (< code > -< / code > ) to match a range of characters is not limited to letters. It also works to match a range of numbers.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								For example, < code > /[0-5]/< / code >  matches any number between < code > 0< / code >  and < code > 5< / code > , including the < code > 0< / code >  and < code > 5< / code > .
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								Also, it is possible to combine a range of letters and numbers in a single character set.

								Create a single regex that matches a range of letters between < code > h< / code >  and < code > s< / code > , and a range of numbers between < code > 2< / code >  and < code > 6< / code > . Remember to include the appropriate flags in the regex.
