How can I determine if a string begins with another string

Question

With the help of code snippets, can you tell me how I can determine if a string begins with another string?

Answer 1

To determine if a string begins with another string in JavaScript , use the startsWith() method:

let str = "Hello, world!";
let result = str.startsWith("Hello"); // true

Use string.startsWith(substring) to check if a string begins with another string. It returns true or false.
