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:
ts
function foo() {
return 2;
console.log("this will never be executed");
}Examples of correct code for this rule:
