What is Hoisting?

This content originally appeared on DEV Community and was authored by Mohammad Mojahidul Islam

In JavaScript, variables and functions are moved, or "hoisted," to the top of their containing scope. This process is known as hoisting. When a variable or a function is declared, the declaration is hoisted to the top of its containing scope. This means we can access them before they are explicitly declared in the code. However, their values are not hoisted, so we can only access the value of a variable after the line where it is initialized.
