Operator Whitespace

In coding, assigning a value using an assignment operator is a common task. However, it is important to note that adding whitespace, such as spaces or tabs, around assignment operators can improve readability and aid in debugging. This guideline recommends that all assignment operators have whitespace on both sides.

Why use whitespace around assignment operators?

Using whitespace around assignment operators can have a number of benefits, including:

• Improved readability: Adding whitespace makes it easier to distinguish the assignment operator from other operators, such as the mathematical operators. This can help make the code more readable and easier to understand.
• Consistency: By always adding whitespace around assignment operators, you can ensure that your code has a consistent look and feel. This can make it easier to maintain and debug.
• Avoiding errors: Adding whitespace can help prevent syntax errors, such as accidentally using the assignment operator instead of the equality operator (which uses two equals signs).

Example code

// Without whitespace
x=y+1;

// With whitespace
x = y + 1;

Notice how in the first example, the assignment operator is immediately followed by the variable, which can make it difficult to distinguish from other operators. In the second example, however, the whitespace around the assignment operator makes it clear that it is indeed an assignment, which can make the code more readable and less prone to errors.

Conclusion

Adding whitespace around assignment operators is a simple but effective way to improve the readability and maintainability of your code. By adopting this guideline, you can make your code easier to read, debug, and maintain, which can save you time and effort in the long run.
