Conditional statements

Often when writing code, you always need to perform different actions for different decisions. You can use conditional statements in your code to accomplish this task.

In JavaScript, we can use the following conditional statements:

• If statement-use this statement to execute code only if the specified condition is true
• If...else Statement-executes code when the condition is true and executes other code when the condition is false
• If...else If....else Statement-Use this statement to select one of several code blocks to execute

If...else if...else Statements

if (condition 1) {code  executed when condition 1 is true}else if (condition 2) {code executed when condition  2 is true}else{  code executed when condition 1 and condition 2 are not true}
