💻 Code
type ILifetime = {
onShareTimeline: () => string
}
function createObject<D>(obj: D & ILifetime & ThisType<D>) {
console.warn(obj)
}
// working
createObject({
title: 'demo',
onShareTimeline() {
return ''
}
})
// not working
createObject({
title: 'demo',
onShareTimeline() {
return this.title
}
})

The generic type is broken
🙂 Expected behavior
