The example of if/else

We use if/else to know what we want in the function. For example,

 

Let num=10

 

If (num>0) {

        Console.log(“the number is positive.”)

Else(num<0)

        Console.log(“the number is negative.”)

}

 

In this function, we can easily know the answer is “the number is positive” so we can quickly find out what the answer we want. Our code uses if/else statements to take action in response to various scenarios. An if/else statement can be used, for instance, to determine if a user is signed in before displaying certain content on a web page to them or to determine whether they have provided a valid password before granting them access to a system.

 

Programmers use if/else statements as a fundamental building block to create code that can respond intelligently to various inputs or circumstances. We may increase the adaptability, flexibility, and user-friendliness of our applications by employing if/else statements.
