docs/src/rules/no-class-assign.md
ClassDeclaration creates a variable, and we can modify the variable.
class A { }
A = 0;
But the modification is a mistake in most cases.
This rule is aimed to flag modifying variables of class declarations.
Examples of incorrect code for this rule:
::: incorrect
/*eslint no-class-assign: "error"*/
class A { }
A = 0;
:::
::: incorrect
/*eslint no-class-assign: "error"*/
A = 0;
class A { }
:::
::: incorrect
/*eslint no-class-assign: "error"*/
class A {
b() {
A = 0;
}
}
:::
::: incorrect
/*eslint no-class-assign: "error"*/
let A = class A {
b() {
A = 0;
// `let A` is shadowed by the class name.
}
}

Examples of correct code for this rule:
::: correct
/*eslint no-class-assign: "error"*/
let A = class A { }
A = 0; // A is a variable.
:::
::: correct
/*eslint no-class-assign: "error"*/
let A = class {
b() {
A = 0; // A is a variable.
}
}
:::
::: correct
/*eslint no-class-assign: 2*/
class A {
b(A) {
A = 0; // A is a parameter.
}
}

This rule has no options.
If you don't want to be notified about modifying variables of class declarations, you can safely disable this rule.
