noLabelVar (since v0.7.0)

This rule is recommended by Rome.

Disallow labels that share a name with a variable

Examples

Invalid

const x1 = "test";
x1: expr;

error[js/noLabelVar]: Do not use the x1 variable name as a label
  ┌─ js/noLabelVar.js:2:1
  │
1 │ const x1 = "test";
  │       -- The variable is declared here
2 │ x1: expr;
  │ ^^

=  note: Creating a label with the same name as an in-scope variable leads to confusion.

Valid

const x = "test";
z: expr;
