faststringmap VS stringFormatter

We were using Go map[string]int to validate the strings and obtain the index in the list. However the map lookups were consuming a lot of compute time. I wondered whether this could be significantly reduced. I looked around and didn't immediately find anything. So I came up with https://github.com/sensiblecodeio/faststringmap which gave us a 5x performance improvement on map lookups and a 25% reduction in overall CSV processing time.

Today we could say that there is one more text formatting utility/lib that has all fmt features, and this library processes text faster, which in some cases could be important. Please give us a star on GitHub and subscribe.

Performance is a key thing of everything, we (humans) don't like to wait and waste our time. Therefore, sometimes quick solution as most of the managers suppose are better than slow but with good engineering and design. But today we are not speaking about management, but about code performance. We have a small text formatting library that allows us to format text using a template in convenient on our view way. These not only formatting function do what fmt.Sprintf does in more convenient way but also provide an additional features. Previous versions of our module were loose in performance to fmt.Sprintf, but since 1.0.1 we are better. And today we are going to tell how to make any golang code work faster.

It’s not very convenient because we have to pass the "Smith" argument twice. And that’s just one duplicate value, imagine how confusing it would get if we had to deal with a whole bunch of them. So, after scratching my head for a little while, I decided to invent my own wheel and make a string formatting like those in C# or Python available in golang. I made a little library currently consisting of two formatting functions which you can find here. My functions allow me to format a string using either indexed {0}, {1}:
