A usage example from the jest-leak-detector README.
(async function () {
let reference = {};
let isLeaking;
const detector = new LeakDetector(reference, {
shouldGenerateV8HeapSnapshot: true,
});
// Reference is held in memory.
isLeaking = await detector.isLeaking();
console.log(isLeaking); // true
// We destroy the only reference to the object.
