Javascript Block Vs Scope. a block statement is used to group zero or more statements. the key difference between block scope and function scope is that function scope refers to variables defined within functions, while block scope refers to variables defined in a pair of curly braces. In es6, const and let keywords allow developers to declare variables in the block scope, which means those variables exist only within the corresponding block. a block scope is the area within if, switch conditions or for and while loops. with the advent of es6, javascript was introduced with a new type of scope, let and const allows us to declare and use the variables with block. javascript variables have 3 types of scope: The block is delimited by a pair of braces (curly. Generally speaking, whenever you see {curly brackets}, it is a block. basically, the difference between function scope and block scope is that in a language that uses function. You can say that function scope is a subset of block scope. In this post i'll outline the three different types of scopes and how they behave in javascript. scope is the location where a variable is defined and the context where other pieces of your code can access and manipulate it.
