Loops

TypeScript's classic counted loop has three parts in parentheses separated by semicolons. Go's for keeps the three parts but drops the parens. Pick the idiomatic Go translation.

About this theme

Go has one loop keyword: for. Three shapes:

for i := 0; i < n; i++ { ... } — classic.
for cond { ... } — while-style.
for { ... } — infinite, exit via break or return.

No while, no do. continue, break, and labelled breaks behave as you'd expect. The range form is its own theme (next module).
