Q. What does /[^(]* regular expression indicate ?

(A) Match one or more characters that are not open paranthesis
(B) Match zero or more characters that are open paranthesis
(C) Match zero or more characters that are not open paranthesis
(D) Match one or more characters that are open paranthesis

💬 Discuss

✅ Correct Answer: (C) Match zero or more characters that are not open paranthesis

Explanation: We should always be careful while using * and ? as repetition characters as they may match zero instances of whatever precedes them, they are allowed to match nothing.

Q. What will be the result when non greedy repetition is used on the pattern /a+?b/ ?

(A) Matches the letter b preceded by the fewest number of a’s possible
(B) Matches the letter b preceded by any number of a
(C) Matches letter a preceded by letter b, in the stack order
(D) None of the mentioned

💬 Discuss

✅ Correct Answer: (A) Matches the letter b preceded by the fewest number of a’s possible

Explanation: Using non greedy repetition may not always produce the results you expect. /a+?b/ matches the letter b preceded by the fewest number of a’s possible.
