let, const, iyo var waxaa loo isticmaalaa in lagu qeexo variables.

let name = "Adam";
const age = 25;
var city = "Hargeisa";

Markaad isticmaaleyso let iyo const, waa muhiim inaad fahamto farqiga u dhexeeya labada. const waxaa loo isticmaalaa si loo xakameeyo qiimaha aan la bedeli karin.

Functions in JavaScript

Function-ku waa habka loo abaabulo code-ka iyo in la sameeyo hawlo gaar ah.

function greet(name) {
  return `Hello, ${name}!`;
}
console.log(greet("Adam"));

Waa muhiim inaad si fiican u fahamto sida loo sameeyo functions si loo fududeeyo maamulka code-kaaga.

Arrays in JavaScript

Arrays waxaa loo isticmaalaa in lagu keydiyo xog badan.

let fruits = ["apple", "banana", "orange"];
fruits.push("grape");
console.log(fruits);

Waa in aad ka digtoonaato in aad isticmaasho array-ka si aan habboonayn, gaar ahaan haddii ay tahay array waaweyn oo leh xog badan.

Functions and Methods in Arrays

Methods-ka Array-ka

Arrays waxay leeyihiin methods kala duwan sida map(), filter(), iyo reduce().

let numbers = [1, 2, 3, 4, 5];
let doubled = numbers.map(num => num * 2);
console.log(doubled);

Isticmaalka map() wuxuu ku siinayaa array cusub iyadoo la adeegsanayo hawl gaar ah oo ku saabsan xogta array-ga.
