Scope: Scope generally means the visibility and accessibililty of variables in different parts of your code. Understanding of differnt types of scopes helps us write error free and clear code. Global Scope: Global scope means the variable is having its accessibility anywhere in the program, inside function or blocks etc. But sometimes it leads to naming conflicts. e.g: let global = "I'm a global variable"; function display(){ console.log(global); } display(); // "I'm a global variable" In this example, global is declared in the global scope and can be accessed inside the display function. Local Scope: The variables are only accessible within a function not outside of it. e.g: function local(){ var local = "I'm a local scope variable"; if (true){ console.log(local);// Works here also inside of if block } } Block Scope: The variables are accessed within that block not outside of it.…
