Patch

View in context: https://bugs.webkit.org/attachment.cgi?id=455591&action=review

The patch overall looks great! Some comments.

Could you explain a bit more detail about this?

1. What problem happens (in which code)
2. Why does it happen?
3. What is the solution to that?

> Source/WebCore/workers/WorkerEventLoop.cpp:77
> +const String WorkerEventLoop::taskMode()

`const` is not necessary as it is copying value.

> Source/WebCore/workers/WorkerRunLoop.cpp:75
> +    const String mode() const

Return `const String&`.

> Source/WebCore/workers/WorkerRunLoop.cpp:174
> +    JSC::JSRunLoopTimer::TimerNotificationCallback timerAddedTask = createSharedTask<JSC::JSRunLoopTimer::TimerNotificationType>([this, predicateMode] {

Let's pass via WTFMove(predicateMode) instead of copying.
