Disallow modifying variables of class declarations (no-class-assign)

ClassDeclaration creates a variable, and we can modify the variable.

class A { }
A = 0;

But the modification is a mistake in most case.

Rule Details

This rule is aimed to flag modifying variables of class declarations.

The following patterns are considered warnings:

class A { }
A = 0;

A = 0;
class A { }

class A {
    b() {
        A = 0;
    }
}

let A = class A {
    b() {
        A = 0; // `let A` is shadowed by the class name.
    }
}

The following patterns are not considered warnings:

let A = class A { }
A = 0; // A is a variable.

let A = class {
    b() {
        A = 0; // A is a variable.
    }
}

class A {
    b(A) {
        A = 0; // A is a parameter.
    }
}

If you don’t want to be notified about modifying variables of class declarations, you can safely disable this rule.

This rule was introduced in ESLint 1.0.0-rc-1.
