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.

4. JavaScript Logical Operators. We use logical operators to perform logical operations on boolean expressions. For example, const x = 5, y = 3; console.log((x < 6) && (y < 5)); // Output: true. Here, && is the logical operator AND. Since both x < 6 and y < 5 are true, the combined result is true. Commonly Used Logical Operators

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:

Mar 10, 2023 · There are three types of logical operators in Javascript: (NOT): Converts operator to boolean and returns flipped value. Below all the JavaScript Logical Operators are explained with the example: NOT (!) Operator: It reverses the boolean result of the operand (or condition). It Converts the operand to boolean type i.e true/false. Syntax:

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)

Understand all types of JavaScript logical operators with clear examples. Learn how to use AND, OR, NOT, and more to simplify your coding logic effectively.

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.

Logical operators. Programming in general is all about logic, so of course we need some logical operators as well. In JavaScript, you will find three primary logical operators: The OR operator: || The AND operator: && The NOT operator: !

Summary: in this tutorial, you will learn how to use the JavaScript logical operators including the logical NOT operator ( !), the logical AND operator ( &&) and the logical OR operator ( ||). The logical operators are important in JavaScript because they allow you to compare variables and do something based on the result of that comparison.
