JavaScript map() method in 7 minutes! 🗺️

[@BroCodez]

// .map() = accepts a callback and applies that function
// to each element of an array, then return a new array
// ------------ EXAMPLE 1 ------------
const numbers = [1, 2, 3, 4, 5];
const squared = numbers.map(square);
const cubed = numbers.map(cube);
console.log(cubed);
function square(element){
return Math.pow(element, 2);
}
function cube(element){
return Math.pow(element, 3);
}
// ------------ EXAMPLE 2 ------------
const students = ["Spongebob", "Patrick", "Squidward", "Sandy"];
const studentsUpper = students.map(upperCase);
const studentsLower = students.map(lowerCase);
console.log(studentsLower);
function upperCase(element){
return element.toUpperCase();
}
function lowerCase(element){
return element.toLowerCase();
}
// ------------ EXAMPLE 3 ------------
const dates = ["2024-1-10", "2025-2-20", "2026-3-30"];
const formattedDates = dates.map(formatDates);
console.log(formattedDates);
function formatDates(element){
const parts = element.split("-");
return `${parts[1]}/${parts[2]}/${parts[0]}`;
}

THANK YOUUUUUUUUUUUUUUUUU

[@ENDTIM3SPRODUCTIONS]

@BroCodez can you do a Lua full course

[@ahmedo0o0]

Thank you for your great work. I have a question.
Is it better to write:
const studentsUpper = students.map(element => element.toUpperCase())
console.log(studentsUpper);
instead of write a function? I've heard that the way I just wrote it more modern and even has a better readablitiy. Is it true? Of course unless we are gonna re-use it then I think a function is a better way.
Thanks again.
