Checking string starts with another
To check if a string starts with another, we can use the built-in startsWith() method in JavaScript.
The startsWith() method takes the search string as an argument and returns true if a search string is found; otherwise, it returns false.
Here is an example:
const str = 'this is my name'console.log(str.startsWith('this'));
Output:
true
By default, the string searching starts from position 0. We can also change its position by passing the second argument.
const str = 'this is my name';console.log(str.startsWith('my',8));
Output:
true
Note: The above method is case-sensitive.

)
