Any says nothing
The interface type that specifies zero methods is known as the empty interface: interface{} An empty interface may hold values of any type. (Every type implements at least zero methods.) Empty interfaces are used by code that handles values of unknown type. With Go 1.18 the predeclared type any became an alias for an empty…
Konika SitoulaUsing a filename as a function input
While creating a new function that reads the file, passing the filename as an argument is not considered best practice and might have negative effects such as making it difficult to write test cases for a variety of criteria. Suppose we want to implement a function to count the number of empty lines in a…
Ignoring how defer arguments are evaluated
In order to understand how arguments are processed using the defer keyword, let’s consider a specific example. Suppose we have a function that needs to execute two other functions, called foo and bar. Additionally, this function needs to handle some status information related to its execution. We can use the defer keyword to ensure that…
Thinking concurrency is always faster
Many developers mistakenly believe that a concurrent solution will always be faster than a sequential one, but this is not always the case. The performance of a solution depends on various factors, such as the efficiency of the concurrency structure, the parts that can be processed in parallel, and the level of contention among the…
Common Anti-patterns with React
Nested components When a component is defined inside another component, it creates a tight coupling between the two components, meaning that they are highly dependent on one another. This can make it difficult to reuse or re purpose the inner component. Also when the parent component re-renders , the inner component will be defined again…
