JavaScript Operators

Operators are symbols used in JavaScript to perform various operations, such as arithmetic, comparison, and logical operations. Here's a brief overview of some of the most common operators in JavaScript:

Arithmetic Operators in JavaScript

Arithmetic operators are used to perform mathematical calculations.

Here are some examples:

Examples :

3 + 5; // => 8
7 - 2; // => 5
4 * 6; // => 24
10 / 2; // => 5
9 % 2; // => 1

Comparison Operators in JavaScript

Comparison operators are used to compare two values and return a Boolean value (true or false).

Here are some examples:

Examples :

3 == 3; // => true
7 > 2; // => true
4 < 6; // => true
10 != 2; // => true
9 <= 9; // => true
9 >= 9; // => true
9 === 9; // => true
"9" === 9; // => false
"9" !== 9; // => true

Logical Operators

Logical operators are used to combine multiple conditions and return a Boolean value (true or false). Here are some examples:

Assignment Operators

Assignment operators are used to assign a value to a variable. Here are some examples:

Other Operators

There are many other operators in JavaScript, including:

The typeof operator, which returns the data type of a value.

The delete operator, which deletes a property from an object.

The in operator, which checks if a property exists in an object.

The instanceof operator, which checks if an object is an instance of a specific class.

By understanding these various operators and how to use them, you'll be able to write more powerful and complex JavaScript code.
