* `[in] script`: A JavaScript string containing the script to execute.

* `[out] result`: The value resulting from having executed the script.

This function executes a string of JavaScript code and returns its result with

the following caveats:

* Unlike `eval`, this function does not allow the script to access the current

lexical scope, and therefore also does not allow to access the

[module scope][], meaning that pseudo-globals such as `require` will not be

available.

* The script can access the [global scope][]. Function and `var` declarations

in the script will be added to the [`global`][] object. Variable declarations

made using `let` and `const` will be visible globally, but will not be added

to the [`global`][] object.

* The value of `this` is [`global`][] within the script.
