Go (also known as Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Because Go's memory management architecture makes concurrency easier, many developers prefer it over traditional languages.

In this course, you will learn the core constructs and techniques of Go as well as advanced concepts of the language. In particular, you’ll learn how to program efficiently by becoming aware of the pitfalls and patterns that are commonly encountered in Go and by building your own applications.

Once you’ve completed this course, you will be able to write concurrent programs and improve the performance of existing ones, thus creating a more robust experience for everyone. Concurrency is in high demand today since it enables developers to reduce execution time of applications significantly, and Golang provides a very rich support for achieving this.

Concurrency in Go

## Problem breakdown

LLet’s break down the question and write the code step by step. We’re provided with the structs. Now, let’s initialize buffer channels with a capacity of `10`.

```go
jobs := make(chan Job, 10)
results := make(chan Result, 10)
```

Write a function to calculate the sum of digits. For this, we’ll need a little bit of algorithmic knowledge. Initialize `sum` to `0`. Take the integer and perform the modulo operation with `10`. The operation will return the last digit. Keep dividing the quotient by `10` until the quotient is `0`. In each iteration, add the remainder in the `sum`.
