JavaScript

const myWebStack = ['JavaScript', 'HTML', 'CSS', 'somtimes PHP', 'sometimes Python', 'sometimes SaSS'];


function addAMessageToInput(elm) {
	console.log(`${elm} language`);
}

// this how we execute a custom function using map and forEach methods

myWebStack.forEach(addAMessageToInput);
 
myWebStack.map(addAMessageToInput);

// both return the same thing

/* 
"JavaScript language"
"HTML language"
"CSS language"
"somtimes PHP language"
"sometimes Python language"
"sometimes SaSS language"
