Explain Conditions in JavaScript?

Programming Language
#1

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.

Syntax

if (condition) {
  //  block of code to be executed if the condition is true
}

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

Syntax

if (condition1) {

  //  block of code to be executed if condition1 is true

} else if (condition2) {

  //  block of code to be executed if the condition1 is false and condition2 is true

} else {

  //  block of code to be executed if the condition1 is false and condition2 is false

}

The Switch statement is used to perform different actions based on different conditions.

Syntax

switch(expression) {

  case x:

    // code block

    break;

  case y:

    // code block

    break;

  default:

    // code block

}
