Difference between single and double quotes in Javascript?

They both represent strings.

 

Which ever one you start with, must be the same one you end the string with.

 

There is really no difference in the end between using single or double quotes, meaning they both represent a string in the end. The system doesn't really care which one you use (but you might?).

the only difference is use single quotes where you want double quotes to appear inside the string (e.g. for html attributes), or vice versa.

 

No need to escape the other character within a string. So a double quoted string can have single quotes without escaping them, and a single quoted string can have double quotes within it without having to escape them.

 

"Double quotes with a single ( ' ) quote in the middle"

'Single quotes with a double ( " ) quote in the middle'

 

Each type must escape their own type

 

"double quotes ( \" ) must escape a double quote"

'single quotes ( \' ) must escape a single quote'

 

Thank you!
