You need to define a function calculateInterestGrowth() that calculates the value of an investment, given the principal, interest rate, compound rate, and time as parameters. - To make the calculator more error proof, you need to provide default values for the interest rate (0.05), compound rate (12), and time period (10 years). - To calculate an exponent in JavaScript, you can use two asterisks ** between the base number and the exponent. For example, 2 ** 3 is 2 to the

If you're new to JavaScript or programming in general, calculating the compound interest can be a fun project! The formula for compound interest is \( A = P (1 + \frac{r}{n})^{nt} \) where \( A \) is your future investment value, \( P \) is the principal investment, \( r \) is the annual interest rate (as a decimal), \( n \) is the number of times interest is compounded per year, and \( t \) is the number of years the money is invested for. Now, let's bring this function to life! You can start by defining your function, setting the parameters with default values, and then implement the formula. Here’s a quick example to get you inspired: ```javascript function calculateInterestGrowth(principal, interestRate = 0.05, compoundRate = 12, time = 10) { return principal * (1 + interestRate / compoundRate) ** (compoundRate * time); } ``` Bam! You have a function that can grow your money in a snap. Whether it’s for savings or a future investment, this little script packs a powerful punch!
