Key Points

• Learn about different types of JavaScript operators including arithmetic, assignment, comparison, logical, ternary, and typeof operators.
• Understand how to perform calculations, assign values, compare data, and make decisions in your code.
• Gain practical skills through examples and coding demonstrations.

Introduction

In this crash course on JavaScript operators, we will explore what operators are, how they work, and how to use them effectively to manipulate data and perform logical checks. By the end of this video, you will be equipped with the knowledge to use operators in your JavaScript projects. Introduction to Operators

Types of Operators

JavaScript operators are symbols that allow you to perform various operations on values, known as operands. The main types of operators we will cover include:

• Arithmetic Operators: Used for basic math operations like addition, subtraction, multiplication, and division. Arithmetic Operators Overview
• Assignment Operators: Used to assign values to variables. Assignment Operators Explained
• Comparison Operators: Used to compare values and return true or false. Comparison Operators Breakdown
• Logical Operators: Combine multiple conditions using AND, OR, and NOT. Logical Operators Introduction
• Ternary Operator: A shorthand for if-else statements. Ternary Operator Usage
• Typeof Operator: Checks the type of a value. Typeof Operator Explanation

Arithmetic Operators

Arithmetic operators allow you to perform calculations:

• Addition: Represented by +, e.g., let sum = 10 + 5; results in 15. Addition Example
• Subtraction: Represented by -, e.g., let difference = 10 - 5; results in 5. Subtraction Example
• Multiplication: Represented by *, e.g., let product = 10 * 5; results in 50. Multiplication Example
• Division: Represented by /, e.g., let quotient = 10 / 2; results in 5. Division Example
• Modulus: Gives the remainder of a division, represented by %. Modulus Example
• Increment and Decrement: Use ++ to increment and -- to decrement a value. Increment/Decrement Example

Assignment Operators

Assignment operators are used to assign values to variables:

• Basic Assignment: = assigns a value, e.g., let x = 9; Basic Assignment
• Addition Assignment: += adds and assigns, e.g., x += 5; Addition Assignment
• Subtraction Assignment: -= subtracts and assigns, e.g., y -= 3; Subtraction Assignment
• Multiplication Assignment: *= multiplies and assigns, e.g., a *= 5; Multiplication Assignment
• Division Assignment: /= divides and assigns, e.g., b /= 3; Division Assignment

Comparison Operators

Comparison operators compare two values and return true or false:

• Equal: == checks for equality, e.g., a == b; Equal Example
• Strict Equal: === checks for both value and type equality. Strict Equal Example
• Not Equal: != checks for inequality. Not Equal Example
• Greater Than: > checks if one value is greater than another. Greater Than Example
• Less Than: < checks if one value is less than another. Less Than Example

Logical Operators

Logical operators combine multiple conditions:

• AND: && returns true if both conditions are true. AND Operator Example
• OR: || returns true if at least one condition is true. OR Operator Example

Ternary Operator

The ternary operator is a shorthand for if-else statements:

let canVote = (age >= 18) ? 'Yes' : 'No';
``` [Ternary Operator Example](#jumpTo:2406)

## Typeof Operator

The typeof operator checks the type of a value:
```javascript
console.log(typeof 'Hello'); // 'string'
``` [Typeof Operator Example](#jumpTo:2550)

## Conclusion

By understanding these operators, you can effectively manipulate data, perform calculations, and make logical decisions in your JavaScript code. Practice using these operators to become more comfortable with JavaScript programming. [Conclusion and Wrap Up](#jumpTo:2714)
