NOTE: this rule is part of the recommended rule set.

Enable full set in deno.json:

{
  "lint": {
    "rules": {
      "tags": ["recommended"]
    }
  }
}

Enable full set using the Deno CLI:

deno lint --rules-tags=recommended

This rule can be explictly included to or excluded from the rules present in the current tag by adding it to the include or exclude array in deno.json:

{
  "lint": {
    "rules": {
      "include": ["no-class-assign"],
      "exclude": ["no-class-assign"]
    }
  }
}

Disallows modifying variables of class declarations.

Declaring a class such as class A {}, creates a variable A. Like any variable this can be modified or reassigned. In most cases this is a mistake and not what was intended.

Invalid:

class A {}
A = 0; // reassigning the class variable itself

Valid:

class A {}
let c = new A();
c = 0; // reassigning the variable `c`
