### What is JavaScript Operators?

In this tutorial, you will learn about different operators available in JavaScript and how to use them with the help of examples.

**What is an Operator?**

An operator in JavaScript, is a symbol that is used to perform any assigned particular operation to operands (values and variables). For example,

let x = 10;

let y = 20;

document.write(x + y);

output:-

30

**Here + is an operator that performs addition, and x and y are operands.**

**JavaScript Operator Types**

Here is a list of different operators you will learn in this tutorial.

- Assignment Operators
- Arithmetic Operators
- Comparison Operators
- Logical Operators
- String Operators
- Other Operators

**JavaScript Assignment Operators**

Assignment operators are used to assign any particular values to variables. For example,

let x = 10;

Here, the = operator is used to assign value 5 to variable x.

**Here’s a list of commonly used assignment operators:**

Operator | Name | Example |

“=” | Assignment operator | a = 7; // 7 |

“=+” | Addition assignment | a += 5; // a = a + 5 |

“-+” | Subtraction Assignment | a -= 2; // a = a – 2 |

“*=” | Multiplication Assignment | a *= 3; // a = a * 3 |

“/=” | Division Assignment | a /= 2; // a = a / 2 |

“%=” | Remainder Assignment | a %= 2; // a = a % 2 |

“**=” | Exponentiation Assignment |

**JavaScript Arithmetic Operators**

Arithmetic operators are used to perform arithmetic calculations. For example,

**const number = 10 + 20; // 30**

Here, the + operator is used to add two operands.

Operator | Name | Example |

“+“ | Addition | x + y |

“–“ | Subtraction | x – y |

“*“ | Multiplication | x * y |

“/“ | Division | x / y |

“%“ | Remainder | x % y |

“++“ | Increment (increments by 1) | ++x or x++ |

“—“ | Decrement (decrements by 1) | –x or x– |

“**“ | Exponentiation (Power) | x ** y |

**JavaScript Comparison Operators**

Comparison operators compare two values and return a boolean value, either true or false. Comparison operators are used in decision-making and loops.

For example,

const a = 5, b = 4;

console.log(a > b); // true

Here, the comparison operator > is used to compare whether a is greater than b.

Operator | Name | Example |

“==“ | Equal to: returns true if the operands are equal | x == y |

“!=“ | Not equal to: returns true if the operands are not equal | x != y |

“===“ | Strict equal to: true if the operands are equal and of the same type | x === y |

“!==“ | Strict not equal to: true if the operands are equal but of different type or not equal at all | x !== y |

“>“ | Greater than: true if left operand is greater than the right operand | x > y |

“>=“ | Greater than or equal to: true if left operand is greater than or equal to the right operand | x >= y |

“<“ | Less than: true if the left operand is less than the right operand | x < y |

“<=“ | Less than or equal to: true if the left operand is less than or equal to the right operand | x <= y |

**Example of Comparision Operator**

**JavaScript Logical Operators**

Logical operators perform logical operations and return a **boolean value**, either true or false.

Logical operators are used in decision making and loops.

For example,

const x = 8, y = 9;

(x < 10) && (y < 20); // true

Here, && is the logical operator AND. Since both x < 10 and y < 20 are true, the result is **true**.

Operator | Description | Example |

“&&“ | Logical AND: true if both the operands are true, else returns false | x && y |

“||“ | Logical OR: true if either of the operands is true; returns false if both are false | x || y |

“ ! “ | Logical NOT: true if the operand is false and vice-versa. | !x |

Example of Logical Operators in JavaScript

**JavaScript String Operators**

In JavaScript, you can also use the + operator to concatenate (join) two or more strings.

**Example of String operators in JavaScript**

**Output**:-

JavaScript is Awesome

**Other JavaScript Operators**

Here’s a list of other operators available in JavaScript. All this Operator is used as per requirment.

Operator | Name | Example |

“,“ | Evaluates multiple operands and returns the value of the last operand | let a = (1, 3 , 4); // 4 |

“?:“ | Returns value based on the condition | (5 > 3) ? ‘success’ : ‘error’; // “success” |

“delete“ | Deletes an object’s property, or an element of an array | delete x |

“typeof“ | Returns a string indicating the data type | typeof 3; // “number” |

“void“ | Discards the expression’s return value | void(x) |

“in“ | Returns true if the specified property is in the object | prop in object |

“instanceof“ | Returns true if the specified object is of of the specified object type | instanceof object_type |
