react/react-in-jsx-scope Suspicious

What it does

Disallow missing React when using JSX

Why is this bad?

When using JSX, <a /> expands to React.createElement("a"). Therefore the React variable must be in scope.

Examples

Examples of incorrect code for this rule:

var a = <a />;

Examples of correct code for this rule:

import React from "react";
var a = <a />;
