JavaScript is a powerful programming language used by millions of developers worldwide. It’s known for its simplicity and versatility, making it an ideal choice for web development, game development, and more. One crucial aspect of JavaScript are logical operators, which allow you to combine multiple conditions into one statement.
This guide will explore logical operators in-depth, including their syntax, usage, and best practices.
What Are Logical Operators?
Logical operators are symbols or keywords used to connect two or more expressions together. They evaluate each expression’s truthiness or falsiness before returning a final value. There are three primary logical operators in JavaScript: && (and), || (or), and ! (not). Let's examine each operator individually.
The AND Operator (&&)
The && operator returns true if both operands are true; otherwise, it returns false. Here's an example:
const x = 5;
const y = 10;
console.log(x > 3 && y < 20); // Returns true because both conditions are met
