2. Write a function called celsiusToFahrenheit that takes an array of Celsius temperatures as input returns an array of converted values to Fahrenheit.
|
||
|
- Create a new variable inside the function called convertedArray.
|
||
|
- Use the map() method to convert each temperature to Fahrenheit and save it into the variable.

3. Write a function called areAllEven that takes an array of numbers as input and returns a boolean which determines if all the numbers given are even or not.
|
||
|
- Create a new variable inside the function called isEven.
|
||
|
- Use the every() method to check if all the numbers are even and save the result into the variable.

|
- Create a new variable called filteredNum
|
||
|
- Use the filter() method to create a new array of only the even numbers from the original array save it in the filteredNum variable.

|
- Create a new variable called productNames
|
||
|
- Use the map() method to return only the product names of each product object into a new array which we can save in the productNames variable.
