bookChallenge: Modify Array Elements Using map()

Task

You are given an array of numbers representing temperatures in Celsius. Your task is to use the map() method to create a new array, converting each temperature to Fahrenheit.

  1. Use the map() method to create a new array called fahrenheitTemperatures by converting each temperature from Celsius to Fahrenheit.
    • The conversion formula is: F = (C * 1.8) + 32, where F is Fahrenheit and C is Celsius.
  2. Log the initial array celsiusTemperatures to the console.
  3. Log the modified array fahrenheitTemperatures to the console.

              
12345678910

            
// Initial array
const celsiusTemperatures = [0, 25, 100, -5, 15];

const fahrenheitTemperatures = ___.___((celsius) => {
  return celsius * ___ + ___;
});

// Log the initial and modified arrays
console.log("Initial array:", celsiusTemperatures);
console.log("Modified array:", fahrenheitTemperatures);
copy

Expected output:

Initial array: 0, 25, 100, -5, 15
Modified array: 32, 77, 212, 23, 59
  1. To create a new array using the map() method, remember to call map() on the original array and provide a callback function that defines the transformation for each element.
  2. Use this formula (F = (C * 1.8) + 32) inside the callback function.

              
12345678910

            
// Initial array
const celsiusTemperatures = [0, 25, 100, -5, 15];

const fahrenheitTemperatures = celsiusTemperatures.map((celsius) => {
  return celsius * 1.8 + 32;
});

// Log the initial and modified arrays
console.log("Initial array:", celsiusTemperatures);
console.log("Modified array:", fahrenheitTemperatures);
copy

Var allt tydligt?
