Comparing Undefined, Null, and Not Defined in JavaScript | #shorts #short #coding #javascript


In JavaScript, there are three common values that can be used to represent missing or uninitialized variables: undefined, null, and not defined. While they might seem similar at first, they actually have distinct meanings and behaviors that can affect the behavior of your code. In this video, we'll explore the differences between these three values and when to use each one. We'll start by looking at undefined, which is typically used for variables that have been declared but not yet assigned a value. We'll then move on to null, which represents a deliberate absence of any object value. Finally, we'll discuss not defined, which occurs when a variable is used without ever being declared. Throughout the video, we'll provide examples and demonstrations to help you understand these concepts in a practical way. Whether you're new to JavaScript or an experienced developer, understanding the differences between undefined, null, and not defined is essential for writing robust and reliable code. So sit back, grab your favorite code editor, and let's dive in!

Best Way to Check 'Null', 'Undefined' or 'Empty' in JavaScript | JavaScript Tutorial for Beginners


How to check if result is not 'Null', 'Undefined' or 'Empty' in JavaScript while using conditions? Lets discuss 'if not undefined, null or empty condition in javascript'. What is the best way to check if data is not null, not undefined and not empty in if else condition using JavaScript? In JavaScript we display data or record if it exists, if it's not null, if it's not undefined and if it's not empty - otherwise we display a message, something like, 'no records found!'. Let's say we have data. We want to display this data, only if it's not empty, it's not undefined and not null. How can we do that easily? what is the best way of doing it? There are several ways to check if data is null, undefined or empty but in conditions, we don't check that. Single line of code can check all these. Also, first handle the error, and in case of the error, stop code execution. In case of no error, proceed and show something. If you are writing an if condition, you don’t need to check if something is empty or undefined or null. It will automatically be considered as false. Javascript has a set of pre-defined falsy values. Those are: false 0 (zero) '' or "" (empty string) null undefined NaN (Not a Number) So undefined, empty and null are falsy. If these are false, then, in 'if else condition' we only need to check if data is true or false. In case of true we proceed. In case of false we display error message. So checking falsy or false is sufficient for 'undefined', 'empty' or 'null'. Do not check undefined, null or empty by using JavaScript 'comparison operators'. Check if the result is "falsy" (i.e., null, undefined, 0, '', false) So this simple check is all you need to check whether data is undefined, null, empty or not any of these in JavaScript. This is a common javascript interview question. So keep it mind as well. Video has solution for following questions: How to check if a variable is Null or Empty in JavaScript?

The difference between undefined, null and NaN in Javascript


This video covers falsey values, the identity operator and the isNaN function. I try to explain not just how Javascript behaves, but provide somewhat of a rationale for this behavior. Summary: undefined — The default value of a variable that has been declared but not assigned a value null — A value meaning "nothing" or "no value" that is useful to assign to variables or return from functions NaN — The result of an invalid mathematical operation, or failure to convert a non-numerical value to a number equality operator () — Operator which does type conversion before comparison identity operator (=) — Operator which does not do type conversion Number.isNAN — The correct way to check if a variable is NaN #Javascript #Null #Programming For more similar tutorials: 🤍

javascript - typeof !== "undefined" vs. != null


#short #javascript #coding-style I often see JavaScript code which checks for undefined parameters etc. this way: if (typeof input ! "undefined") { // do stuff } This seems kind of wasteful, since it involves both a type lookup and a string comparison, not to mention its verbosity. It's needed because undefined could be renamed, though. My question is: How is that code any better than this approach: if (null != input) { // do stuff } As far as I know, you can't redefine null, so it's not going to break unexpectedly. And, because of the type-coercion of the != operator, this checks for both undefined and null... which is often exactly what you want (e.g. for optional function parameters). Yet this form does not seem widespread, and it even causes JSLint to yell at you for using the evil != operator. Why is this considered bad style?
