If Statement in Javascript

In Javascript, the if statement is used for conditional branching, allowing us to execute a block of code if a specified condition evaluates to true.

The `if` condition can be followed by optional `else if` and `else` statements to execute different blocks of code based on different conditions.

If Statement:

Syntax:

if (condition) {
  // Code to be executed if the condition is true
}

In the below example, we were checking the `if` condition statement `count > 8` then it will print code inside if block Otherwise nothing will get print.

Example:

let count = 10;

if (count > 8) {
  console.log("count is greater than 8");
}

Note: code inside if condition will only be executed if the condition x > 8 is true.

If-Else Statement:

We can use an "else" block to specify code that should be executed if the condition is false.

Example:

let count = 8;

// condition statement if `count > 7` then it will print code inside `if` block otherwise `else` block.
if (count > 7) {
  console.log("count is greater than 7");
} else {
  console.log("count is less than 7");
}

If - else If - else Statement:

We can extend the if-else structure to include multiple conditions using "else if".

Example:

let count = 8;

if (count > 10) {
  console.log("count is greater than 10");

} else if (count >= 5) {
  console.log("count is equal to 5 or greater than 5 but not greater than 10");

} else {
  console.log("count is less than 5");
}

Ternary Operator:

The ternary operator `(? :)` provides a concise way to write simple if-else statements.

Example:

let count = 9;

let result = count > 10 ? "count is greater than 10" : "count is less than 10";

console.log(result);

Nested If-else Statements:

We can nest if statements within each other to create more complex conditional logic.

Example:

let count = 30;

if (count > 10) {
  if (count < 15) {
    console.log("count is between 10 and 15");
  } else {
    console.log("count is greater than or equal to 15");
  }
} else {
  console.log("count is 10 or less");
}
