JavaScript and Its Functions

  1. Function Declarations : Function declarations consist of the function keyword, a name of the function, a pair of parenthesis around zero or more parameters and a pair of curly braces. A typical function declaration:
function printMyName(x) {
console.log(x)
}
printMyName('Wreet')
//expected output: 'Wreet'
const addTen = function(x) { return x + 10};
console.log(addTen(5));
//expected output : '15'
const doubled = (x) => x*2;
console.log(doubled(10))
//expected output: '20'
function printNames(...names){
for (name in names){
console.log(name)
}
}
printNames('abc', 'def', 'ghi');
// expected output: 'abc', 'def', 'ghi'
