The tag requires you to specify the name of the parameter you are documenting. tag provides the name, type, and description of a function parameter.But for this article, we are going to focus on below 3 tags: JSDoc comes with lots of tags, you can checkout them all on it's website. To handle such and more complex scenarios, and make sure intellisense works right for those, we will use JSDoc's and block tags. Without proper intellisense, we often make typos, call the method which doesn't exist or even try to access the properties of an objects by a random guess. So, now if you check for blank JSON, intellisense will stop working, because now VS code doesn't know the types. But, it's unlikely that your variable is going to hold values with initialization. In above example, after you write first line, let foo = 42 it will show you methods of a number:īut what if you assign a JSON, which is going to hold many properties like id, createdOn, etc. Visual Studio Code's intellisense will only work, if it understands the type of your code. Variables in JavaScript are not directly associated with any particular value type, and any variable can be assigned (and re-assigned) values of all types: let foo = 42 // foo is now a numberįoo = true // foo is now a boolean Intellisense in VS Code JavaScript is a loosely typed and dynamic language.
