White space refers to the use of spacing within your code or writing so that the text on a page can be read more easily.

For example, when wanting to give the impression that you have created a table.

Most languages such as C#, JavaScript, HTML etc. do not read white space so you can format your code however you like. This makes it readable for you, and doesn’t change how your computer reads it.

However, other programming languages are heavily reliant on spacing in order for them to understand the code. Formatting to make things easier for you to read in this case could mean that your program won’t behave as your expect.
