Using special characters like %e2%97%8e%dc%ab%e2%97%8e and %e2%98%ba as variable names might seem creative, but in the world of JavaScript, it's a big no-no. Why is that so? Let's dive into the details.
JavaScript variable names must follow specific rules to be valid. One crucial rule is that variable names can only contain letters (both uppercase and lowercase), numbers, underscores, or dollar signs. Other characters like emojis, symbols, or weird combinations of characters are simply not allowed in variable names.
When you create a variable in JavaScript, you are essentially defining a storage location in memory to hold a value. The variable name serves as the label for that location, helping you reference and manipulate the stored value easily. So, using non-standard characters as variable names can confuse the JavaScript interpreter and lead to errors.
Imagine trying to remember or reference a variable named %e2%97%8e%dc%ab%e2%97%8e in your code. How would you even pronounce that, let alone remember it for later use? Choosing clear and meaningful variable names is essential for writing readable and maintainable code.
Additionally, JavaScript has reserved keywords that serve specific purposes in the language. Using special characters in variable names might inadvertently clash with these reserved keywords, causing unexpected behavior or syntax errors in your code. Keeping your variable names simple and relevant helps avoid such conflicts.
To illustrate, consider the unconventional name %e2%98%ba for a variable. When you try to use this variable in your JavaScript code, the interpreter might get confused or throw an error because %e2%98%ba does not adhere to the standard naming conventions.
In a nutshell, sticking to standard naming conventions for variables in JavaScript, such as starting with a letter, using alphanumeric characters and underscores, and avoiding reserved keywords, ensures the clarity and correctness of your code. This practice is not just a matter of aesthetics; it directly impacts the readability and maintainability of your codebase.
So next time you're tempted to get creative with your variable names by using exotic characters or emojis, remember that simplicity and clarity pave the way for efficient and bug-free JavaScript coding. Stick to the rules, choose meaningful names, and let your code shine with readability and reliability!
