Hot to access detailed variable information in tagged template literals like property name?-CodePudding

If I have a function that returns a tagged template literal I can console log the function toString() and it will show me the object and property name of my variable.

function myfN() {
 return tag`Test ${data.name}`
}
    
// this console logs the information I would need inside my tag, see below.
console.log(myfN.toString())

console output >>>>
function myfN() {
 return tag(_templateObject || (_templateObject = (0, _taggedTemplateLiteral2["default"])(["Test ", ""])), data.name);
}

as you can see data.name is in the log result, now when we look inside my tag function I have my strings and values

function tag(literals, ...vars) {
  console.log(literals.raw);
  console.log(vars);

  // get here that the literals are using `data.name`
}

Is there any way to get the variable names inside my tag without passing the whole object as a value into the string? Everything

CodePudding user response：

As with other functions, you can't access variable name that is used to pass data into it. There also may be no variable at all:

tag`Test ${"look, ma! No variables!"}`

Only way to get variable name (if there any) and use it would be parsing and manipulating code, for example with babel.
