Foundations

TypeScript uses let and const to introduce variables; the type is inferred or annotated explicitly. Go has two short forms for the same job: - name := value — the **short de…

TypeScript has one number type. Go has many: int, int8, int16, int32, int64, uint* mirrors, float32, and float64. The big idea: **Go has no implicit numeric conve…

Go strings are immutable byte sequences. There are no template literals — fmt.Sprintf does the job. A byte is an alias for uint8; a rune is int32 and represents a Unicode…

if/else looks familiar — no parentheses, braces required. The one new shape is the short-statement-if: if err := work(); err != nil { ... }. It scopes a temporary to the…

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 `ret…

Functions look familiar — func name(args) returnType { ... } — with one big new idea: multiple return values. Go functions can return a tuple, and the convention for "this mi…
