some information about the constructor function in js

we can normally add the multi-line words as the keys to the object but using the constructor function it cannot be possible
for instance:

function User(current_sal){
this."updated salary" // not possible
//or
this.[current_sal] // not possible
}

Start by locating the tutorial section covering constructor functions and reviewing the shown attempts to use quoted and computed property names. Clarify how these object properties should be expressed in a constructor, and consider the work complete when the section explains the supported syntax with a working example.
