06. Loops
Ek kaam baar-baar — for aur while.
Is chapter me cover hoga:
- for loop
- while loop
- kab kaunsa
1. Loop kyun?
1 se 10 print karna ho to 10 baar console.log nahi likhte. Loop bolta hai: itni baar dohrao.
2. for loop
for (let i = 1; i <= 5; i++)
• start: i = 1
• condition: i <= 5
• har baar i badhao (i++)
3. while
Tab tak chalo jab tak condition true hai. Dhyan: condition kabhi false honi chahiye, warna infinite loop.
Practice — count 1 to 5
for loop se 1–5 print karo.
