Same as: no-console

Description

Disallow the use of console.

In a browser environment, it’s considered a best practice to log messages using console. Such messages are considered to be for debugging purposes and therefore not suitable to ship to the client. In general, calls using console should be stripped before being pushed to production.

Examples

Invalid

console.error('hello world')
