🍮Conditions

In JavaScript, you can use the if statement to execute a block of code if a certain condition is true. You can also use the else statement to execute a block of code if the condition is false, and the else if statement to specify additional conditions.

Here is an example of how you might use the if, else, and else if statements in JavaScript:

let x = 10;

if (x > 0) {
  console.log("x is positive");
} else if (x < 0) {
  console.log("x is negative");
} else {
  console.log("x is zero");
}

In this example, the code inside the first if block will be executed if the value of x is greater than 0. If the value of x is not greater than 0, the code inside the else if block will be executed if the value of x is less than 0. If the value of x is neither greater than 0 nor less than 0 (i.e., it is equal to 0), the code inside the else block will be executed.

The if, else, and else if statements allow you to specify different blocks of code to be executed depending on the value of a particular condition. This is useful for controlling the flow of your program based on different input or conditions.
