Introduction
In this lab, we will explore the concept of the logical not operator in JavaScript. Specifically, we will create a function that takes a boolean value and returns its inverse using the ! operator. Through this exercise, you will gain a deeper understanding of how logical operations work in JavaScript and how they can be used in everyday programming tasks.
Using Logical Not Operator in JavaScript
To start practicing coding in JavaScript, open the Terminal/SSH and type node.
The logical not operator (!) returns the inverse of the given value. Below is an example implementation of the logical not function in JavaScript:
const not = (a) => !a;
You can use the not function to return the inverse of a given value. Here are some examples:
not(true); // false
not(false); // true
Summary
Congratulations! You have completed the Logical Not lab. You can practice more labs in LabEx to improve your skills.
