Question

I have to match 2 strings where at least one word is same, I need to give a success msg.

var str1 = "Hello World";
var str2 = "world is beautiful";

I need to match/compare these 2 strings, in both strings world is matching, So i need to print a success message. How do I go about it.

Answer 1

The following code will output all the matching words in the both strings:

var words1 = str1.split(/\s+/g),
    words2 = str2.split(/\s+/g),
    i,
    j;

for (i = 0; i < words1.length; i++) {
    for (j = 0; j < words2.length; j++) {
        if (words1[i].toLowerCase() == words2[j].toLowerCase()) {
           console.log('word '+words1[i]+' was found in both strings');
        }
    }
}
