Predict whether a character search lands on or next to its destination.
Before this lesson: Compose an edit; word and quotation lessons.
f finds a character to the right on the current line; t stops just before it. F searches left; T stops just after the found character. ; repeats the original search and comma reverses its direction. They do not cross lines. A count chooses a later occurrence, such as 2f,.
On “red, blue, green”, f, from r lands on the first comma; t, lands on d. From g, F, lands on the comma before green; T, lands on the following space. The target character survives a dt edit.
const message = \"red, blue, green\";
