Scope And The Scope Chain In Javascript Pdf Scope Computer Science These two keywords provide block scope in javascript. variables declared with let and const inside a code block are "block scoped," meaning they are only accessible within that block. Scope determines where a variable can be accessed or used within a javascript program. it helps control the visibility and lifetime of variables in different parts of the code.
