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.
