Lecture 1: Introduction to JavaScript

Overview: In this lecture, we introduced the basics of JavaScript for beginners, drawing comparisons with Python to help you get comfortable with JavaScript’s syntax and features.

Key Topics Covered:

• Introduction to JavaScript: Understanding its importance for web development.
• Printing Output: How to use console.log() to display information.
• Declaring Variables: Learning to declare and assign variables using let, const, and var.

By the end of this lecture, you’ll be able to print messages to the console and work with simple variables in JavaScript.

Lecture 2: Data Types and Operators in JavaScript

Overview:

In this lecture, we explored JavaScript’s data types and operators, essential building blocks for any JavaScript program. We built on concepts from the first lecture and introduced both primitive and non-primitive data types, along with various operators to manipulate and evaluate data.

Key Topics Covered:

1. Data Types:

   • Primitive: Number, String, Boolean, Undefined, Null, Symbol, and BigInt.
   • Non-Primitive: Object and Array.
   • Using typeof to determine variable types.

2. Operators:

   • Arithmetic: Performing calculations with +, -, *, /, %, and **.
   • Assignment: Assigning and updating values with =, +=, -=, etc.
   • Comparison: Comparing values with ==, ===, !=, !==, <, >, <=, and >=.
   • Logical: Combining conditions with &&, ||, and !.
   • Bitwise: Manipulating binary representations with &, |, ^, ~, <<, >>, and >>>.

Learning Outcomes:

By the end of this lecture, you’ll be able to:

• Identify and use different data types in JavaScript.
• Apply various operators to manipulate and evaluate data.
• Write simple programs that combine these concepts to solve problems.

Practice these skills and experiment with examples to deepen your understanding!
