+Go compiles into native machine code.
+Go handles Unicode natively thus any character can be used in a string.
+Divided into packages, where a package is sort of a library, except for main which defines an executable.
+Import declarations **must** follow the package declaration.
+Function declarations: `func <name> (<param list>) (<result list>)`. 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 `_`.
