After strings.Split, get the last element?

[xobk...@gmail.com]

In general, how can I get the last element of an array or a slice?

In particular, after split a string, how can I get the last element?

info := strings.Split("a=1,b=2,c=3,d=4", ",")

lastInfo := info[len(info)-1]

detail := strings.Split(lastInfo, "=")

seems a little awkward ...

`x[len(x)-1]` is the way to do so, and was chosen compared to x[-1] both for explicit clarity, and to avoid subtle bugs.

As a side note, len(x) is very cheap to evaluate at runtime, though negative indexing would have had to do that same computation anyway.
