As a coder, you are often faced with the conundrum. Do I choose single quotes or double quotes?
Alas, in some languages, single quote is reserved for defining single characters only but other languages give you the options of using either. Sometimes double quotes imply variable interpolation, but you shouldn’t be bothering with that anyway. Single quote is better than double quote for the following reason that you don’t Have to hold shift to type a single quote.
Double quotes for user facing strings. Reason: easier to extract for i18n, or even to understand what is and isn’t ultimately shown.
