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;
suspicious/noLabelVar.js:2:1 lint/suspicious/noLabelVar ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✖ Do not use the x1 variable name as a label
1 │ const x1 = "test";
> 2 │ x1: expr;
│ ^^
3 │
ℹ The variable is declared here
> 1 │ const x1 = "test";
│ ^^
2 │ x1: expr;

ℹ Creating a label with the same name as an in-scope variable leads to confusion.
Valid
const x = "test";
z: expr;
