Diagnostic Category: lint/style/noRestrictedGlobals

JavaScript (and super languages)

Since: v1.0.0 Sources:

Same as: no-restricted-globals

Description

This rule allows you to specify global variable names that you don’t want to use in your application.

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.

Examples

Invalid

console.log(event)

code-block.js:1:13 lint/style/noRestrictedGlobals ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  ⚠ Do not use the global variable event.
  
  > 1 │ console.log(event)
      │             ^^^^^
    2 │ 
  
  ℹ Use a local variable instead.

Valid

function f(event) {
    console.log(event)
}

Options

Use the options to specify additional globals that you want to restrict in your source code.

{
    "//": "...",
    "options": {
        "deniedGlobals": ["$", "MooTools"]
    }
}

In the example above, the rule will emit a diagnostics if tried to use $ or MooTools without creating a local variable.
