Lint Rules

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;
    3 │ 
  
  ℹ Creating a label with the same name as an in-scope variable leads to confusion.

Valid

const x = "test";
z: expr;
