Go (aka Golang) Practice Exercises: Essential Techniques for Mastering the Framework

Here’s a practice exercise to help you build your skills with Go:

  1. Create a new Go file and declare a variable of type int.
  2. Write a function that takes an int parameter and adds it to the variable. Call the function with a few different values and print the variable after each call.
  3. Create a slice that contains a few strings.
  4. Use a loop to iterate through the slice and print each string to the console.
  5. Write a function that takes a string parameter and returns the string reversed. Call the function with a few different strings and print the result.
  6. Use the “time” package to measure the execution time of a block of code. For example, measure the time it takes to sort a large slice of integers.
  7. Finally, compile and run the program to make sure it works as expected.

This exercise covers some basic concepts and syntax of Go, including variables, functions, slices, loops, packages, and performance profiling. By completing this exercise, you will gain practical experience with Go and be on your way to mastering this powerful programming language.
