What common mistakes can be made when writing code in Go?

When writing code in Go, the following common mistakes are often encountered:

• Incorrect use of pointers and values. For example, accidentally copying large structures instead of passing by pointer, which leads to performance loss.

• Ignoring errors. It is customary in Go to explicitly check errors after function calls, but sometimes developers forget to do this, which can lead to hidden bugs.

• Incorrect use of goroutines. For example, forgetting to synchronize access to shared data or not closing channels, which causes leaks or data races.

• Poor code formatting. Go has a built-in tool gofmt that standardizes code style. Not following this standard makes reading and maintaining code more difficult.

• Using global variables unnecessarily. This reduces modularity and complicates testing.

• Inefficient use of slices and maps. For example, improper memory allocation or not releasing resources.

Attentive attention to these aspects helps in writing more reliable and maintainable Go code.
