Stress is the force applied to a material, while strain is the resulting deformation or change in shape.
Stress is the force applied per unit area on a material.
Strain is the measure of deformation or change in shape of a material.
Stress and strain are related by the material's modulus of elasticity.
Example: When a weight is placed on a spring, the stress on the spring increases, causing it to deform (strain).
Poisson's ratio is a measure of the ratio of lateral strain to longitudinal strain in a material subjected to stress.
Poisson's ratio is denoted by the symbol 'ν'.
It is a dimensionless quantity that typically ranges between 0 and 0.5.
A material with a Poisson's ratio of 0.5 would mean that it does not change in lateral dimensions when stretched longitudinally.
Common materials like rubber have a Poisson's ratio close to

Event loop is a mechanism that allows JavaScript to perform non-blocking I/O operations.
Event loop is a part of JavaScript runtime that continuously checks the call stack and the task queue.
It executes the tasks in the task queue one by one, and once the task is completed, it is removed from the queue.
Event loop ensures that the JavaScript code does not block the main thread and allows for asynchronous programming.

var is function-scoped while let is block-scoped.
var declarations are hoisted to the top of their scope while let declarations are not.
var can be redeclared in the same scope while let cannot.
let is preferred over var for better code readability and avoiding unexpected behavior.
Example: var x = 10; if (true) { var x = 20; } console.log(x); // Output: 20 let y = 10; if (true) { let y = 20; } console.log(y
Prototype is a property of an object that allows adding new properties and methods to an existing object.
Prototype is a blueprint for creating objects.
It is used to add new properties and methods to an existing object.
All objects in JavaScript have a prototype property.
The prototype property is used to share properties and methods between objects.
Modifying the prototype of an object affects all instances of that object
Javascript is single threaded.
Javascript has a single call stack and event loop.
It can handle asynchronous operations through callbacks and promises.
Web workers can be used for multi-threading in Javascript.
