Single vs Double Quotes?

Learning JS. Strings can be represented with either single quotes or double quotes and I’m wondering if there is any functional difference. Is there no such thing as a char in this language that needs to be used with single quotes? It seems as if the primitive data type is the String.

You are correct about there being no char in JS, only string. The quotes have no functional difference. Where we might want to use both, one as an outer pair, and one as an inner pair is if the string contains a quote.

As of ES2015 we also have string template literals which are denoted by backticks. Those all also legal quotes for all intents and purposes.

Given that advantage, it makes escapement a thing of the past.
