Calling a function using the new keyword creates a new instance of the function's constructor.

You can import all exports of a file as an object in JavaScript using the 'import * as' syntax.
Use the 'import * as' syntax followed by the object name and 'from' keyword to import all exports of a file as an object.
For example: import * as myExports from './myFile.js';
You can then access the exports using dot notation, like myExports.myFunction().
The 'this' operator in JavaScript refers to the current context or object.
Refers to the current object or context in which a function is being executed
Can be used to access properties and methods of the current object
The value of 'this' is determined by how a function is called

Arrow functions are defined using the '=>' syntax.
They have a shorter syntax compared to traditional function expressions.
They do not have their own 'this' keyword, instead they inherit it from the parent scope.
Example: const add = (a, b) => a + b;
