let quotedText = /'([^']*)'/;
console.log(quotedText.exec("she said 'hello'"));
//["'hello'", "hello"]
why does hello appear twice?
The first element in the result is the full match, and the second element is the first captured group. Remove the parentheses () to get only one result.
let quotedText = /'[^']*'/;
console.log(quotedText.exec("she said 'hello'"));If you still want to keep the parentheses, you can use a non-capturing group as shown below:
let quotedText = /'(?:[^']*)'/;
console.log(quotedText.exec("she said 'hello'"));
