Javascript Regular Expression:Non Greedy Matching

You can force a quantifier (*, +, ?, {m}, {m,}, or {m,n}) to be

nongreedy by following it with a question mark. Doing so forces the expression

to match the minimum number of characters rather than the maximum.

Code:

var pattern =/(ma.*?ing)/

var sentence = "Regular Expression matching can be daunting task"

pattern.test(sentence)

console.log(RegExp.$1)

Output:

matching

Explanation:

The output shows that the interpreter found the first shortest matching pattern in

the string
