Rule: no-inferrable-types

Disallows explicit type declarations for variables or parameters initialized to a number, string, or boolean.

Rationale

Explicit types where they can be easily infered by the compiler make code more verbose.

Config

One argument may be optionally provided:

  • ignore-params allows specifying an inferrable type annotation for function params. This can be useful when combining with the typedef rule.
Examples
"no-inferrable-types": true
"no-inferrable-types": [true, "ignore-params"]
Schema
{
  "type": "array",
  "items": {
    "type": "string",
    "enum": [
      "ignore-params"
    ]
  },
  "minLength": 0,
  "maxLength": 1
}
