How to check if a string starts with another in JavaScript
Checking if a string starts with another substring is a common thing to do. See how to perform this check in JavaScript
ES6, introduced in 2015, added the startsWith() method to the String object prototype.
This is the way to perform this check in modern JavaScript
This means you can call startsWith() on any string, provide a substring, and check if the result returns true or false:
'testing'.startsWith('test') //true
'going on testing'.startsWith('test') //false
This method accepts a second parameter, which lets you specify at which character you want to start checking:
'testing'.startsWith('test', 2) //false
'going on testing'.startsWith('test', 9) //true
