Control Flow in JavaScript: if, else, and switch Explained with Real Examples

Programming is not just about writing code — it's about making decisions . Just like humans decide what to do based on situations, programs use control flow to choose different paths depending on conditions. In this article, you'll learn the core control flow tools in JavaScript: if if-else else if switch We'll use simple real-life analogies and short programs to make everything crystal clear. Let's dive in! 🚀 🚦 What Is Control Flow? Control flow determines the order in which code is executed . Normally, code runs line by line from top to bottom . But sometimes we want it to branch based on a condition. Think of a traffic signal : 🔴 Red → Stop 🟡 Yellow → Slow down 🟢 Green → Go JavaScript works the same way — it checks a condition and decides which block of code to run . ✅ The if Statement The if statement runs a block of code only when a condition is true .
