Comparison and Logical operators are used to test for true or false. Comparison operators are used in logical statements to determine equality or difference between variables or values. Given that x = 5, the table below explains the comparison operators:

Dec 13, 2024 · Logical operators in JavaScript are used to perform logical operations on values and return either true or false. These operators are commonly used in decision-making statements like if or while loops to control the flow of execution based on conditions.

Jun 5, 2022 · There are four logical operators in JavaScript: || (OR), && (AND), ! (NOT), ?? (Nullish Coalescing). Here we cover the first three, the ?? operator is in the next article. Although they are called “logical”, they can be applied to values of any type, not only boolean. Their result can also be of any type. Let’s see the details. || (OR)

In this tutorial, you will learn how to use JavaScript logical operators including logical NOT (!) AND (&&), and OR (|) operators.

Nov 29, 2023 · Logical operators in JavaScript let developers perform operations on values or expressions, playing a crucial role in effective decision-making within code. The primary logical operators are && (AND), || (OR), and ! (NOT). Let's look at each one now. 1. AND (&&) Operator.

Comparison operators compare two values and return a boolean value (true or false). For example, console.log(a > b); // Output: true . Here, we have used the > comparison operator to check whether a (whose value is 3) is greater than b (whose value is 2). Since 3 is greater than 2, we get true as output.

The logical operators in JavaScript are generally used with Boolean operands and return a boolean value. There are mainly three types on logical operators in JavaScript - && (AND), || (OR), and ! (NOT). These operators are used to control the flow the program.

In JavaScript, we have three main logical operators: Let's dive into each of these operators and see how they work their magic! The AND operator (&&) is like a strict parent – it only returns true if both of its operands are true. If either operand is false, the result is false. Let's look at some examples: let hasID = true;

Logical operators are pivotal for controlling the flow and decision-making in JavaScript. This guide is crafted to help beginners understand and effectively use JavaScript's logical operators— &&, ||, !, and !! —complete with comprehensive and fully explained examples.

Learn about the key logical operators in JavaScript, including AND, OR, NOT, XOR, short-circuit evaluation, and the ternary operator.
