Finished the Mandatory, done Extra but have an error on the Add function2 for the piping.js. Not started the Magic-8-balls.js yet. |
| function multiply() { | ||
| // Calculate the result of the function and return it | ||
| return 3 * 4; |

Whilst this does work for the result below, it's not going to work for other numbers. The Exercise asked for this function to work with input parameters to multiple together.

|
||
| var result = divide(3, 4); | ||
| function divide() { | ||
| return 3 / 4; |

Again, this is not using function parameters. Can you figure out how this function would look using them?
| function createGreeting() { | ||
| let name = "Daniel"; | ||
| let greeting = "Hello, my name is "; | ||
| let fullGreeting = greeting + name; |

Why don't you try using greeting and name as function parameters?
| var mentor5 = "Yohannes"; | ||

| function percentProgram(firstNumber, secondNumber) { | ||
| let overallTotal = firstNumber + secondNumber; |

Here you have demonstrated using function parameters nicely so I'm sure you can correct the other exercises above :)
| function percentProgram(firstNumber, secondNumber) { | ||
| let overallTotal = firstNumber + secondNumber; | ||
|
|
||
| let percentage = Math.floor((firstNumber / overallTotal) * 100); |

Running this exercise returns 65% for students and 34% for mentors. The total is 99% not 100%, can you think why?
| function getNumber() { | ||
| return Math.random() * 10; | ||
| function letterSet() { | ||
| return Math.random() * 10; //Math.random() syntax is a floating-point, pseudo-random number between 0 (inclusive) and 1 (exclusive). |

What you've said here is correct but what else is happening here (look at the * 10)?

Thank you @pads. Each time the code is ran, it will return random values 0 to 9. Result: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

| function concatenate(firstWord, secondWord, thirdWord) { | ||
| // Write the body of this function to concatenate three words together | ||
| // Look at the test case below to understand what to expect in return | ||
|
|
||
| return `${firstWord} ${secondWord} ${thirdWord}`; |
| function formatCurrency(productPrice) { | ||
| let salesTax = 0.2; | ||
| let taxValue = productPrice * salesTax; | ||
| let salesPrice = productPrice + taxValue; |

Have you thought about how you could use your calculateSalesTax function inside this function to achieve the same result? This is a good opportunity to practice call functions inside of functions!

| // Why can this code be seen as bad practice? Comment your answer. | ||
| let badCode = | ||
| let badCode = format(multiply(add(startingValue, 10), 2)); //badCode has all codes mumbled up in one line// |
| let goodCode = | ||
| let sum = add(startingValue, 10); | ||
| let product = multiply(sum, 2); | ||
| let goodCode = format(product); |
