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;
correctness/noLabelVar.js:2:1 lint/correctness/noLabelVar ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

   Do not use the x1 variable name as a label
  
    1 │ const x1 = "test";
  > 2 │ x1: expr;
   ^^
    3 │ 
  
   The variable is declared here
  
  > 1 │ const x1 = "test";
         ^^
    2 │ x1: expr;
    3 │ 
  
   Creating a label with the same name as an in-scope variable leads to confusion.
  

Valid

const x = "test";
z: expr;
