Let's looks at some common mistakes that programmers can make when writing javascript code. and also show you the fix of these mistakes, to make your code safer and easier to understand.

If you run this code in your console, you can see that the console.log() statement within the displayname() function successfully displays the value of the name variable, which is declared in its parent function. this is an example of lexical scoping, which describes how a parser resolves variable names when functions are nested. Understanding variables is fundamental to writing any javascript program. but the nuances between var, let, and const declarations can be confusing.
