This field exists only in the root `Scope` object (the global scope). It provides information about implicit global variables. Implicit global variables are variables that are neither built-in nor explicitly declared, but created implicitly by assigning values to undeclared variables in non-strict code. `Variable` objects for these variables are not present in the root `Scope` object's fields `variables` and `set`.

The value of the `implicit` field is an object with two properties.

- **Type:** `Variable[]`

- **Description:** The array of all implicit global variables.

- **Type:** `Map<string, Variable>`

- **Description:** The map from variable names to variable objects for implicit global variables.

::: tip

In `Variable` objects that represent implicit global variables, `references` is always an empty array. You can find references to these variables in the `through` field of the root `Scope` object (the global scope), among other unresolved references.
