No semicolons, unless multiple statements on 1 line. -`gofmt` mandatory. `goimports` (`golang.org/x/tools/cmd/goimports`) manages imports. -Slices are dynamically sized arrays that can be accessed `s[i]` or a subset can be taken `s[i:j]`. Indexing: half-open (starts at 0). `s[i:j]` yields i through j-1. Either can be omitted. - -Convention: comment describing package preceding package declaration. - -Variables initialised to "zero value".7689 -String concatenation via `+` char. -Supports assignment operators, e.g `+=`, `*=` etc -Short-hand variable declaration requires no type, it is inferred of the value `:=` **only allowed in a function** - -For-loop structure: -``` -for initialization; condition; post { - // code -} -``` -Either part can be left away with different semantics. -All parts gone: loop forever. -Only condition is like a while x == true; -`range` keyword to loop over a slice or array with `for index, arg := range slice` - -`_` is the blank identifier, thus above if we don' need the index we can put `_`. - -**Type assertion** |
