Builtin JS Functions

Exploring built-in JS functions

Report a typo

Hey there! This problem might be a bit unpredictable, but give it a go and let us know how you do!

Consider the following JavaScript code:


let num = '15.3';
let parsedNum = parseFloat(num);
let sqrtVal = Math.sqrt(parsedNum);
alert(`The square root of ${parsedNum} is ${sqrtVal}`);

What will this code do when executed?

Select one option from the list

It will parse the string 15.3 as a float number, then compute its square root and display the result in an alert box.

It will compute the square root of 15.3 and display the result as a string in an alert box.

It will square the number 15.3 and display the result in an alert box.

It will show a JavaScript error because sqrt() is not a built-in function.
