Enforces the consistent use of either double or single quotes in JSX attributes.
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='"' />
This rule enforces the consistent use of either double or single quotes in JSX attributes.
This rule has a string option:
"prefer-double"
(default) enforces the use of double quotes for all JSX attribute values that don't contain a double quote."prefer-single"
enforces the use of single quotes for all JSX attribute values that don’t contain a single quote.
Examples of incorrect code for this rule with the default "prefer-double"
option:

/*eslint jsx-quotes: ["error", "prefer-double"]*/
<a b='c' />

You can turn this rule off if you don’t use JSX or if you aren’t concerned with a consistent usage of quotes within JSX attributes.
