eslint/no-constructor-return Pedantic

What it does

Disallow returning value from constructor

Why is this bad?

In JavaScript, returning a value in the constructor of a class may be a mistake. Forbidding this pattern prevents mistakes resulting from unfamiliarity with the language or a copy-paste error.

Examples

Examples of incorrect code for this rule:

class C {
  constructor() {
    return 42;
  }
}

Examples of correct code for this rule:

class C {
  constructor() {
    this.value = 42;
  }
}

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny no-constructor-return

Config (.oxlintrc.json)

{
  "rules": {
    "no-constructor-return": "error"
  }
}
