eslint/no-restricted-globals Restriction ​
What it does ​
This rule allows you to specify global variable names that you don't want to use in your application.
Why is this bad? ​
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.
For instance, early Internet Explorer versions exposed the current DOM event as a global variable event, but using this variable has been considered as a bad practice for a long time. Restricting this will make sure this variable isn't used in browser code.
Example ​
If we have options:
json
"no-restricted-globals": ["error", "event"]The following patterns are considered problems:
javascript
function onClick() {
console.log(event); // Unexpected global variable 'event'. Use local parameter instead.
}
