How to Use Simple if/else Statements in JavaScript?

In JavaScript, you can use an if/else statement to control the flow of your program based on a condition.

Here’s an example of a simple if/else statement in JavaScript:

let x = 10;

if (x > 5) {
  console.log("x is greater than 5");
} else {
  console.log("x is less than or equal to 5");
}

In this example, the condition x > 5 is evaluated, and the appropriate block of code (either the if block or the else block) is executed based on the result of the evaluation. In this case, x is 10, so the condition x > 5 is true, and the message “x is greater than 5” is logged to the console.

You can also chain multiple if/else statements together to create more complex conditionals:

let x = 10;

if (x > 15) {
  console.log("x is greater than 15");
} else if (x > 10) {
  console.log("x is greater than 10 but less than or equal to 15");
} else {
  console.log("x is less than or equal to 10");
}

In this example, there are two conditions (x > 15 and x > 10), and the appropriate block of code is executed based on the result of each evaluation. In this case, x is 10, so the condition x > 15 is false, the condition x > 10 is true, and the message “x is greater than 10 but less than or equal to 15” is logged to the console.
