eslint/no-unreachable Nursery

What it does

Disallow unreachable code after return, throw, continue, and break statements.

This rule can be disabled for TypeScript code if allowUnreachableCode: false is configured in the tsconfig.json, as the TypeScript compiler enforces this check.

Why is this bad?

Unreachable code after a return, throw, continue, or break statement can never be run.

Examples

Examples of incorrect code for this rule:

function foo() {
    return 2;
    console.log("this will never be executed");
}

Examples of correct code for this rule:

function foo() {
    console.log("this will be executed");
    return 2;
}

How to use

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

Config (.oxlintrc.json)

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

CLI

oxlint --deny no-unreachable
