Opleiding: Go Programming

Go Intro

The course starts with a discussion of Go's syntax with data types, type inference, arrays, control flow and operators. The difference between rvalues ​​and lvalues ​​is also covered and attention is paid to immutable data.

Functions and Closures

The functions and parameter passing in Go is treated. The distinction between call by value and call by reference is explained. Variadic functions, recursion and closures are also discussed.

Pointers

Then it's time to pay attention to the use of pointers in Go. The difference with pointers in C is explained as well as pointer arithmetic, nil pointers and pointers to pointers.

Classes

Classes in Go are also part of program. The course explains the two ways in which Go offers an alternative to traditional inheritance. The first is embedding and can be seen as an automated form of composition or delegation. The second is the use of Go interfaces, which provide runtime polymorphism.

Error Handling

Also the specific way of error handling in Go with the error and panic interface is discussed. In this respect attention is also paid to the recover interface and the analysis of stack traces.

Concurrency

Finally concurrency in Go with Go routines, sending and receiving with channels and worker pools and synchronization mechanisms are covered.

Audience Course Go Programming

The course Go Programming is intended for developers who want to learn how to program in the Go language and who want to examine its capabilities.

Prerequisites training Go Programming

To participate in this course prior knowledge of and experience with programming in a modern programming language such as Java, C# or Python is necessary.

Realization course Go Programming

The theory is treated on the basis of presentations. Illustrative demos are used to clarify the concepts. There is ample opportunity to practice and theory and exercises are interchanged. The course times are from 9.30 to 16.30.

Certification course Go Programming

Participants receive an official certificate Go Programming after successful completion of the course.
