Understanding the difference between Map and ForEach method
The map method truly shines when you’re dealing with scenarios that involve data transformation. Imagine you have an array of temperatures in Celsius, and you want to convert them to Fahrenheit. Here’s where the map method can elegantly step in:
const celsiusTemperatures = [23, 30, 18, 12, 25];
const fahrenheitTemperatures = celsiusTemperatures.map(celsius => (celsius * 9/5) + 32);
In this example, the map method applies the Fahrenheit conversion formula to each Celsius temperature, creating a new array with the corresponding Fahrenheit values.
