Hi, In javascript can we reference a variable rather creating a

copy with that value??

usecase:
using vuejs.

want to ref the status of a window to a data property, so that i can attach a watcher to watch for changes in that variable,

Objects (including arrays and functions) are always passed by reference const obj = { a: 42 }; function something(param) { param.a = 100; } something(obj); console.log(obj.a); // 100 Primitives are always passed by value const prim = 42; function something(param) { param = 100; } something(prim); console.log(prim); // 42
