JavaScript – Logical Order in If Else Statements

Posted by

In JavaScript, the logical order of if-else statements is important because it determines the order in which the code is executed. The code inside the first if statement that evaluates to true will be executed, and the code inside all other if statements will be skipped. If none of the if statements evaluate to true, the code inside the else statement will be executed.

Here is an example of a simple if-else statement:

[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]

let x = 5;

if (x > 10) {
  console.log("x is greater than 10");
} else {
  console.log("x is not greater than 10");
}

[/dm_code_snippet]

In this example, the if statement checks if the value of x is greater than 10. Since x is not greater than 10, the code inside the else statement will be executed, and “x is not greater than 10” will be printed to the console.

You can also chain multiple if-else statements together to create more complex logic.

[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]

let x = 5;

if (x > 10) {
  console.log("x is greater than 10");
} else if (x < 0) {
  console.log("x is less than 0");
} else {
  console.log("x is between 0 and 10");
}

[/dm_code_snippet]

In this example, the first if statement checks if x is greater than 10. If that evaluates to false, the second if statement checks if x is less than 0. If that also evaluates to false, the code inside the else statement is executed and “x is between 0 and 10” will be printed to the console.

It is important to note that the order of if-else statements is crucial. So, you need to be careful when writing the logical order of the statements.
