What is the output?
console.log(test3);
console.log(test3());
var test3 = function(){return 3;}
console.log(test3);
console.log(test3());
var test3 = function(){return 3;}

🔥 The DSA journey starts NOW!
I’ve started a brand-new Data Structures & Algorithms series! 🚀
And we’re starting with the most important foundation — BIG O NOTATION.
If you’ve ever wondered:
❓ Why is one solution better than another?
❓ How do we measure code efficiency?
❓ What does O(n), O(log n) or O(n²) actually mean?
This first video will make it simple. 💯
🎬 DSA Series — Episode 1: Big O Notation
