I've also used this in cases where I have a menu and some of the items are different depending on the user. It allows for an if this, then that approach to coding, where certain actions or statements will only be executed if certain conditions are met. so the empty array disappears, or our value gets added to the new array. What is Javascript Conditional Statement A javascript conditional statement is a type of programming logic that allows the code to make decisions based on conditions set by the programmer. The array spread syntax throws an error if you give it a false (which works ok for objects) so instead of an & operator, I use a ternary ? operator instead and either return the value in an array, or a blank array. Now you can call your function getUser(username, true) for the full details, and getUser(username, false) if you don't need the extra info! Same pattern for conditionally adding items to arraysĪs I mentioned at the start of this post - you can use a very similar pattern for arrays.
Here's the pattern I use: const myObject = Else If Statement
