Philosophy

gambas was created to serve the needs of Go developers who wanted a robust data analysis package. pandas is an amazing tool, and is considered the industry standard when it comes to data organization and manipulation.

We didn't have a solid alternative in the Go realm. According to the Go Developer Survey 2021 Results, missing critical libraries were one of the most common barriers to using Go. You may have used Go for some time now, but you might've missed some of the libraries you used when you were using Python. gambas aims to scratch that itch. You will be able to tap into the superpowers of pandas while using your favorite language Go.

Go is a very attractive language with a very loyal userbase. It provides a pleasant developer experience with its simple syntax and strong typing. However, Go currently tends to be skewed towards developing services. 49% of projects written in Go are API/RPC services, and another 10% are for web services. The ultimate goal for gambas is to allow the Go programming language to be a major player in the data analysis field.
