|  | ## Match Beginning String Patterns
 | ||
|  | 
 | ||
|  | ## The Problem
 | ||
|  | Use the caret character in a regex to find "Cal" only in the beginning of the string rickyAndCal. | ||
|  | 
 | ||
|  | ### Hint 1:
 | ||
|  | Try surrounding your regexp in slashes  | ||
|  | ```javascript | ||
|  | let testExp = /^test/;  | ||
|  | // returns true or false depending on whether test is found in the beginning of the string | ||
|  | ``` | ||
|  | 
 | ||
|  | ### Hint 2:
 | ||
|  | Try using the '^' character caret outside of brackets as seen in the above example | ||
|  | 
 | ||
|  | ### Spoiler Alert - Solution Ahead
 | ||
|  | 
 | ||
|  | ## Solution
 | ||
|  | ```javascript | ||
|  | let rickyAndCal = "Cal and Ricky both like racing."; | ||
|  | let calRegex = /^Cal/; // Change this line | ||
|  | let result = calRegex.test(rickyAndCal); | ||
|  | ``` |
