Let’s go through Statements in JavaScript in a structured way.

---

📜 Statements in JavaScript

A statement in JavaScript is a command that tells the computer to do something.

• Each statement is usually written on a new line.
• Statements can end with a semicolon ( ; ) (optional in JS, but recommended).

Example:

let x = 10;   // Variable declaration statement
console.log(x); // Function call statement

---

1️⃣ Declaration Statements

Used to declare variables or constants.

var name = "Raj";   // Old way
let age = 20;       // Modern block-scoped
const PI = 3.14;    // Constant

---

2️⃣ Expression Statements

• Produces a value and assigns it or uses it.

let sum = 5 + 10;    // Expression statement
console.log(sum);    // Function call (also a statement)

---

3️⃣ Conditional Statements

Used to make decisions.

if (age >= 18) {
  console.log("Adult");
} else {
  console.log("Minor");
}

switch (day) {
  case 1: console.log("Monday"); break;
  case 2: console.log("Tuesday"); break;
  default: console.log("Other day");
}

---

4️⃣ Loop Statements

Used to repeat tasks.

for (let i = 0; i < 5; i++) {
  console.log(i);   // For loop
}

let n = 0;
while (n < 3) {
  console.log(n);   // While loop
  n++;
}

---

5️⃣ Function Statements

Define reusable blocks of code.

function greet(name) {
  console.log("Hello " + name);
}
greet("Raj");

---

6️⃣ Try-Catch (Error Handling)

Handle errors safely.

try {
  let result = 10 / 0;
  console.log(result);
} catch (error) {
  console.log("Error occurred!");
}

---

7️⃣ Jump Statements

Control the flow of loops.

for (let i = 0; i < 5; i++) {
  if (i === 2) continue; // skips 2
  if (i === 4) break;    // stops loop
  console.log(i);
}

---

8️⃣ Other Common Statements

• return → Ends function and sends back a value.
• throw → Throws an error.
• debugger → Stops execution for debugging in DevTools.

function add(a, b) {
  return a + b;   // return statement
}

✅ Summary

JavaScript statements include:

• 📦 Declaration → var, let, const
• 🧮 Expression → calculations, assignments
• 🔀 Conditional → if, else, switch
• 🔁 Loops → for, while, do...while
• 📞 Functions → function, return
• ⚠️ Error Handling → try...catch, throw
• ⏭️ Jump → break, continue
