2-dars Operatorlar bilan ishlash Operatorlarning turlari

2-dars - Operatorlar bilan ishlash
Operatorlarning turlari:

1. 
   Arithmetic Operators - (Arifmetik operatorlar)
   
2. 
   Comparison (Relational) Operators- (Taqqoslash operatorlari)
   
3. 
   Logical Operators - (Mantiqiy opertatorlar)
   
4. 
   Assignment Operators - (Topshiriq operatorlari)
   
5. 
   Conditional Operators - (Shart opertorlari)
   
6. 
   Type operators
   
7. 
   Ternary operators
   

Raqamlar bilan ishlash
-Raqamga o’tkazish
parseInt('10', 10) === 10;
parseFloat('10.2') === 10.2;

-Satrga o’tkazish

const a = 10.toString(); // Uncaught SyntaxError
const a = 10..toString()
const a = 10..toString()

O’zgaruvchilar bilan ishlash


const , let - Kalit so`zlari orqali
const speedOfCar = 32;
let fristName = 'Shahriyor';

Maxsus simvollar va raqamlar orqali o`zgaruvchilarni yaratish

const 1value = 32; // xato
const value1 = 32; // to'gri
const one+two = 3; // xato
const onePlusTwo = 3; // to'gri
const $price = 3000 // to'gri
const const = “const”; // xato

• 
  camelCase 🐫 - bo'sh joy bilan ajratilmaydi, har bir keyingi so'z katta harf bilan boshlanadi
  
• 
  snake_case 🐍 - bir so`zdan so`ng bo`shliqlar o`rniga pastki chiziqcha qo`yib ajratiladi
  

Arithmetic Operators
‘’+’’ – qo’shish operatori
const a = 5;
const b = 10;
console.log(a+b) // 15
“-“ - ayirish operatori
const a = 5;
const b = 10;
console.log(a-b) // -5
“*” – ko’paytirish operatori
const a = 5;
const b = 10;
console.log(a*b) // 50
“/” – bo’lish operatori
const a = 5;
const b = 10;
console.log(a/b) // 0.5
“%” – qoldiqli bolish operatori
const a = 31;
const b = 10;
console.log(a % b) // 1
“++” – incement operatori
let x = 5;
x++
let z = x;
console.log(z) // 6

“--” - decrement operatori

let x = 5;
x--
let z = x;
console.log(z) // 4
“**” – darajaga ko’paytirish operatori
let x = 5;
let result = x ** 2
console.log(result) // 25

let one = 10;

let z = Math.pow(one, 2)
console.log(z) // 100
