Basic Operators

 

JavaScript has several basic operators that can be used to perform arithmetic, comparison, logical, and assignment operations. Here are some of the most commonly used operators:

1. Arithmetic Operators:

   • Addition (+)
   • Subtraction (-)
   • Multiplication (*)
   • Division (/)
   • Modulus (%)
   • Exponentiation (**)

2. Comparison Operators:

   • Equal to (==)
   • Not equal to (!=)
   • Greater than (>)
   • Less than (<)
   • Greater than or equal to (>=)
   • Less than or equal to (<=)

3. Logical Operators:

   • AND (&&)
   • OR (||)
   • NOT (!)

4. Assignment Operators:

   • Assign (=)
   • Add and assign (+=)
   • Subtract and assign (-=)
   • Multiply and assign (*=)
   • Divide and assign (/=)
   • Modulus and assign (%=)

5. Ternary Operator:

   • Ternary operator (a ? b : c)

These are some of the basic operators in JavaScript that are essential for performing basic operations and building more complex logic.

JavaScript is a programming language that uses several operators to perform different tasks on values and variables. Here are some basic operators in JavaScript with examples:

• Arithmetic operators: Arithmetic operators perform mathematical operations on numerical values.

Example:

javascript

let x = 5;
let y = 2;

console.log(x + y); // Output: 7
console.log(x - y); // Output: 3
console.log(x * y); // Output: 10
console.log(x / y); // Output: 2.5
console.log(x % y); // Output: 1

• Assignment operators: Assignment operators assign a value to a variable.

Example:

javascript

let x = 5;
x += 3; // Same as x = x + 3
console.log(x); // Output: 8

• Comparison operators: Comparison operators compare two values and return a Boolean value (true or false).

Example:

javascript

let x = 5;
let y = 2;

console.log(x > y); // Output: true
console.log(x < y); // Output: false
console.log(x == y); // Output: false
console.log(x != y); // Output: true
console.log(x >= y); // Output: true
console.log(x <= y); // Output: false

• Logical operators: Logical operators are used to combine two or more conditions and return a Boolean value.

Example:

javascript

let x = 5;
let y = 2;

console.log(x > 3 && y < 5); // Output: true
console.log(x > 3 || y > 5); // Output: true
console.log(!(x > y)); // Output: false

• String operators: String operators are used to concatenate strings.

Example:

javascript

let firstName = "John";
let lastName = "Doe";

console.log(firstName + " " + lastName); // Output: "John Doe"

• Conditional (ternary) operator: The conditional (ternary) operator is used to assign a value to a variable based on a condition.

Example:

javascript

let age = 20;
let status = (age >= 18) ? "adult" : "minor";
console.log(status); // Output: "adult"

These are some of the basic operators in JavaScript.
