Conditional Statements

Very often when you write code, you want to perform different actions for different decisions.

You can use conditional statements in your code to do this.

In JavaScript we have the following conditional statements:

    Use if to specify a block of code to be executed, if a specified condition is true
    Use else to specify a block of code to be executed, if the same condition is false
    Use else if to specify a new condition to test, if the first condition is false
    Use switch to specify many alternative blocks of code to be executed

    *********The if Statement***********
*/
//Use the if statement to specify a block of JavaScript code to be executed if a condition is true.
var x=18;

if(x==18)
{
    console.log("your are adult");
}


/*
The else Statement

Use the else statement to specify a block of code to be executed if the condition is false.
*/


if(x==10)
{
    console.log("you are adult");
}
else{
    console.log("you are not adult");
}


/*
**************The else if Statement*************

Use the else if statement to specify a new condition if the first condition is false.

var subject_number=10;
if(subject_number>=80)
{
    console.log("very Good");
}
else if(subject_number<80 && subject_number> 50)
{
    console.log("good");
}
else{
    console.log("you fail");
