The document analyzes the performance of different methods for merging arrays in JavaScript. It shows examples of using the concat() method, spread operator, and push.apply() method to merge the contents of two arrays. The push.apply() method had the best performance at 0.004ms, followed by the spread operator at 0.021ms, with concat() being the slowest at 0.080ms.
The nullish coalescing operator (??) is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined.

The document discusses using the spread operator to conditionally add keys to an object in a cleaner way than using if statements. It shows an example of using the spread operator to add a 'bio', 'books', 'email', or 'website' key to the aboutAuthor object based on their existence in the info object, providing a cleaner alternative to multiple if statements. The spread operator allows checking for a key and adding it to the object in one line, improving readability over separate conditional blocks.

This document compares and contrasts arrays and sets in JavaScript. It notes that sets do not allow duplicate values, while arrays do. Items in an array can be accessed using indexes, but items in a set cannot. The document also provides an example of using a set to remove duplicate values from an array in one line of code.
Arguments is an Array-like object accessible inside functions that contains the values of the arguments passed to that function.

Asynchronous functions make it easier to write asynchronous JavaScript by using the async keyword. Asynchronous functions always return promises, even if a normal value is returned. You should understand JavaScript promises before using asynchronous functions, as they can cause confusion if promises are not understood.

Each type of OutOfMemoryError has different causes, diagnosis approaches and solutions. This session equips you with the knowledge, tools, and techniques needed to troubleshoot and conquer OutOfMemoryError in all its forms, ensuring smoother, more efficient Java applications.
In today's world, artificial intelligence (AI) is transforming the way we learn. This talk will explore how we can use AI tools to enhance our learning experiences. We will try out some AI tools that can help with planning, practicing, researching etc.
But as we embrace these new technologies, we must also ask ourselves: Are we becoming less capable of thinking for ourselves? Do these tools make us smarter, or do they risk dulling our critical thinking skills? This talk will encourage us to think critically about the role of AI in our education. Together, we will discover how to use AI to support our learning journey while still developing our ability to think critically.
Java Architecture
Java follows a unique architecture that enables the "Write Once, Run Anywhere" capability. It is a robust, secure, and platform-independent programming language. Below are the major components of Java Architecture:
1. Java Source Code
Java programs are written using .java files.
These files contain human-readable source code.
2. Java Compiler (javac)
Converts .java files into .class files containing bytecode.
Bytecode is a platform-independent, intermediate representation of your code.
3. Java Virtual Machine (JVM)
Reads the bytecode and converts it into machine code specific to the host machine.
It performs memory management, garbage collection, and handles execution.
4. Java Runtime Environment (JRE)
Provides the environment required to run Java applications.
It includes JVM + Java libraries + runtime components.
5. Java Development Kit (JDK)
Includes the JRE and development tools like the compiler, debugger, etc.
Required for developing Java applications.
Key Features of JVM
Performs just-in-time (JIT) compilation.
Manages memory and threads.
Handles garbage collection.
JVM is platform-dependent, but Java bytecode is platform-independent.
Java Classes and Objects
What is a Class?
A class is a blueprint for creating objects.
It defines properties (fields) and behaviors (methods).
Think of a class as a template.
What is an Object?
An object is a real-world entity created from a class.
It has state and behavior.
Real-life analogy: Class = Blueprint, Object = Actual House
Class Methods and Instances
Class Method (Static Method)
Belongs to the class.
Declared using the static keyword.
Accessed without creating an object.
Instance Method
Belongs to an object.
Can access instance variables.
Inheritance in Java
What is Inheritance?
Allows a class to inherit properties and methods of another class.
Promotes code reuse and hierarchical classification.
Types of Inheritance in Java:
1. Single Inheritance
One subclass inherits from one superclass.
2. Multilevel Inheritance
A subclass inherits from another subclass.
3. Hierarchical Inheritance
Multiple classes inherit from one superclass.
Java does not support multiple inheritance using classes to avoid ambiguity.
Polymorphism in Java
What is Polymorphism?
One method behaves differently based on the context.
Types:
Compile-time Polymorphism (Method Overloading)
Runtime Polymorphism (Method Overriding)
Method Overloading
Same method name, different parameters.
Method Overriding
Subclass redefines the method of the superclass.
Enables dynamic method dispatch.
Interface in Java
What is an Interface?
A collection of abstract methods.
Defines what a class must do, not how.
Helps achieve multiple inheritance.
Features:
All methods are abstract (until Java 8+).
A class can implement multiple interfaces.
Interface defines a contract between unrelated classes.
Abstract Class in Java
What is an Abstract Class?
A class that cannot be instantiated.
Used to provide base functionality and enforce
