First and Foremost:
First and first, programmers should strive to create readable, understandable code. This can be accomplished by giving variables descriptive names, adding comments to the code as needed, and dividing the code up into smaller, easier to handle functions and modules. Additionally, developers should refrain from obfuscating their code or using extraneous acronyms as this might make it more difficult for others to read and maintain.
Another excellent practise is to use local variables whenever possible rather than global variables. Conflicts can result from global variables, which also make it challenging to find faults or unwanted side effects. Developers can encapsulate code and reduce the scope of any potential problems by using local variables.
