Spelling and readability are very important for humans and not important for machines.

TL;DR: Take care of your names.

Problems

• Readability

• Harder to search terms in code.

Solutions

1. Spellcheck your code.

2. Use an IDE with spellchecking

Context

Many of us don't speak English as our first language.

We need to have extra care for our texts and names.

This article has a typo in its title as proof of context and also a clickbait😀

Sample Code

Wrong

comboFeededBySupplyer = supplyer.providers();

Right

comboFedBySupplier = supplier.providers();

Detection

[X] Manual

• We need to read the code in a peer review.

[X] Automatic

• Some IDEs have warnings on the typos.

Tags

• Readability

• Naming

Conclusion

Pay close attention to your names.

You will probably be the person reading the code in a few months.
