Read the product/language docs from cover to cover - preface to the last appendix Just read it - like it was a novel When you get a "goal", you will at least be nominally-acquainted with the language/product capabilities, and you should be able to find what you are looking for relatively quickly That is how I [overview] taught myself to solder back in the 90s And PHP 4 And Opsware SAS And countless other things over the years Sure - it is 'only' head knowledge until you use it: but making yourself aware of what you will later use is vital Heck - it is probably how you learned math back in grade school: there was no "goal", you just learned it It was not until much later that you were able to apply all that knowledge to any goals
