ESLintenforce the consistent use of either double or single quotes in JSX attributes (jsx-quotes)
The --fix option on the command line automatically fixes problems reported by this rule.
JSX attribute values can contain string literals, which are delimited with single or double quotes.
<a b='c' />
<a b="c" />
Unlike string literals in JavaScript, string literals within JSX attributes can’t contain escaped quotes. If you want to have e.g. a double quote within a JSX attribute value, you have to use single quotes as string delimiter.
<a b="'" />
<a b='"' />
