What are the scopes of variables in javascript #javascript #scope #variables #shorts

Scope in JavaScript refers to the context in which variables, functions, and objects are declared and accessible during the runtime of a program. The scope determines where these entities can be referenced and where they are not visible or accessible. JavaScript has three main types of scope: global scope, function scope, and block scope.

JavaScript defines the visibility and accessibility of variables, functions, and objects in different parts of the code. Understanding scope is crucial for managing variables effectively and avoiding unintended side effects in the program.
