Match Beginning String Patterns

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

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

let rickyAndCal = "Cal and Ricky both like racing.";
let calRegex = /^Cal/; // Change this line
let result = calRegex.test(rickyAndCal);
