const code = `
let a = "Hello!"
let b = "Hi!"

const goodMorning = () => {
 const str = "Good morning!"
}
`

const scopes = getVariables(code)
const a_value = scopes[0].vars[0] //will point to variable "a" in global scope
const str_value = scopes[1].vars[0] //will point to variable "str" in goodMorning function 
console.log(canAccess(str_value, a_value, scopes)) //will print true because "str" can access to variable "a" in global scope
```
