Iteration with range
Go 1.22 added a new range form that lets you iterate over an
INTEGER directly — the modern, idiomatic count-up loop. Pick the
Go form that iterates i from 0 through 9.
TypeScript:
``ts
for (let i = 0; i < 10; i++) {
console.log(i);
}
``

About this theme
for i, v := range collection is the workhorse. Over a slice you get (index, value). Over a map you get (key, value). Over a string you get (byteIndex, rune). Over a channel you get just the value, with no index. Use _ to discard either side.
