Rule: no-restricted-globals

Disallow specific global variables.

Disallowing usage of specific global variables can be useful if you want to allow a set of global variables by enabling an environment, but still want to disallow some of those.

Rationale

function broken(evt: Event) {
    // Meant to do something with `evt` but typed it incorrectly.
    Event.target;  // compiler error
    event.target;  // should be a lint failure
}

Early Internet Explorer versions exposed the current DOM event as a global variable 'event',
but using this variable has been considered a bad practice for a long time.
Restricting this will make sure this variable isn’t used in browser code.

Notes:

Config

This rule takes a list of strings, where each string is a global to be restricted. event, name and length are restricted by default.
