Understanding Hoisting: A Crucial Concept in JavaScript
So basically, you can say that Hoisting is like a teacher who collects all the homework before class starts and then hands it out to everyone when class begins. In JavaScript, all variable declarations are collected before the code runs and then assigned values when the code runs. This means that you can use a variable before it has been
JavaScript Hoisting
In JavaScript, a variable declaration is hoisted to the top of the current scope. This means that a variable can be declared after it has been used. For example: index.js. console.log(foo); var foo = ''bar''; The above code will output: foo is not defined. This is because the variable declaration is hoisted to the top of the scope, which means
