"The parseInt() function parses a string and returns an integer. It takes a second argument for the radix, which specifies the base of the number in the string. The radix can be an integer between 2 and 36.

The function call looks like:

parseInt(string, radix);

And here's an example:

var a = parseInt("11", 2);

The radix variable says that "11" is in the binary system, or base 2. This example converts the string "11" to an integer 3.

Use parseInt() in the convertToInteger function so it converts a binary number to an integer and returns it."
