feat: Enhanced Event Loop section with Task Queue vs Microtask Queue …

[AnvayKharb]

This pull request updates the README.md to provide clearer explanations and enhanced coverage of key JavaScript concepts, especially around scope, equality operators, expressions vs statements, and the event loop. The most significant change is the expanded explanation of the JavaScript Event Loop, detailing the distinction and priority between the Task Queue and Microtask Queue. Additional improvements include clarifications in sections on equality operators, scope, and module patterns, as well as minor formatting and organizational adjustments.

Expanded and clarified JavaScript concepts:

• Event Loop and Queues: Added a comprehensive explanation of the Event Loop, including detailed descriptions of the Task Queue (Macrotask Queue) and Microtask Queue, their respective responsibilities, and the execution order priority, emphasizing how microtasks can block macrotasks.
• Equality Operators: Clarified the difference between ==, ===, and typeof operators according to the ECMAScript specification, improving the explanation for better understanding.
• Scope Types: Improved the section on function scope, block scope, and lexical scope, providing more precise definitions based on the ECMAScript specification.
• Expressions vs Statements: Enhanced the explanation of the difference between expressions and statements, including details on function hoisting and invocation rules.

Minor organizational and formatting changes:

• IIFE and Modules: Added a note about the relevance of IIFEs in the context of ES6 modules, clarifying their role in scope isolation.…distinction

• Clearly differentiated Task Queue (Macrotask Queue) and Microtask Queue
• Added comprehensive priority and execution order explanation
• Clarified that Microtask Queue has higher priority than Task Queue
• Detailed correct execution flow with numbered steps
• Added examples of what goes in each queue (setTimeout, DOM events vs Promises, async/await)
• Improved documentation for better understanding of JavaScript's concurrency model

Resolves: Event Loop execution order and queue priority documentation
