How can I reduce the number of errors in my script?

To reduce the number of errors in your script, follow these tips -

• Use lots of comments 强>. Comments enable you to explain why the script is written the way it is and to explain particularly difficult parts of the code.
• Always use indentation to make code easier to read. Indenting statements also makes it easier for you to match opening and closing tags, braces, and other HTML and script elements.
• Write modular code. Whenever possible, group statements into functions. Using functions, you can group related statements and test and reuse parts of your code with minimal effort.
• Be consistent in naming variables and functions. Try to use names that are long enough and meaningful, and describe the contents of the variable or the purpose of the function.
• Use consistent syntax when naming variables and functions. In other words, keep them all lowercase or all uppercase; if you prefer Camel-Back notation, use it consistently.
• Test long scripts in a modular way. In other words, don't try to write the entire script before testing any part of it. Write a section of code and get it running before adding the next section of code.
