1️⃣ Basics Q1: What are var, let, and const? var → function-scoped, hoisted, can re-declare. let → block-scoped, hoisted (temporal dead zone), no re-declare. const → block-scoped, must be initialized, no reassignment. Q2: Difference between == a...
On this topic, we shall learn some advanced JavaScript concepts that’ll enable us have better understanding of JavaScript which can later be applied on frameworks such as React. Topics The topics we shall dwell in on this journey towards Java Arrays...
