Eslint不允许内置的全局函数？

Question

Is there a rule to disable specific built-in JS functions? Eg I want to disable parseFloat because there's almost never cases where parseFloat is better than unary + .

Answer 1

You can use no-restricted-globals :

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.

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

Example:

{
  "rules": {
    "no-restricted-globals": ["parseFloat"]
  }
}

Or, for a more descriptive warning:

{
  "rules": {
    "no-restricted-globals": [
      "error",
      {
        "name": "parseFloat",
        "message": "Use + instead."
      }
    ]
  }
}
