eslint/no-redeclare Pedantic

What it does

Disallow variable redeclaration

Why is this bad?

n JavaScript, it’s possible to redeclare the same variable name using var. This can lead to confusion as to where the variable is actually declared and initialized.

Example

var a = 3;
var a = 10;

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

oxlint --deny no-redeclare

Config (.oxlintrc.json)

{
  "rules": {
    "no-redeclare": "error"
  }
}
