According to many industry experts, Golang is the most important skill to learn in 2022 as more and more companies are using it to build awesome technology - from infrastructure technologies to microservices to serverless programs powering entire SAAS products.
In this course, you will first start with understanding the GO language and its use cases. You will look at basic concepts such as structs, if else, slices, logical operators, floats and calculations, struct methods, loops/range, functions and many more while working on the project—Nutrition calculator. You will then work on Google Trends where you will be working with XML, defining XML data, Get/read Google Trends function, Unmarshal function, printing the trends, and much more.
Finally, you will be working on the project titled Google Translate where you will be learning advanced topics and concepts such as concurrency and parallelism, sequential processing, go-routines, channels, creating queries, parsing JSON, and many more.
By the end of this course, you will be able to approach building new projects with Golang with a better toolset. You will also have built three awesome real-world projects that you can show on your resume to get selected in interviews, use the base code to create other projects, and build a better and deeper knowledge of GO.
What You Will Learn
- Look at the basic overview of GO and the course’s planned trajectory
- Learn about structs, slices, packages and libraries before using them
- Look at the briefing before starting any project
- Work around on a project – Nutrition calculator
- Execute and build project on Google Trends
- Work around on a project of Google Translate
Audience
This course is designed for beginner Golang developers wanting to learn a bit more by building simple to complex projects. Existing developers from other languages wanting to learn Golang will gain a lot from this course.
A very basic Golang knowledge (should have completed the tour of Golang) along with Golang setup on the machine are the only requirements to get started with this course.
