I have array that contain strings

mentArray ={ "words":[ "xyz", "abc", "random", "sample" ] }

And I want to match string

 var ment = "hello world ran"

What I'm doing is

mentArray.words.find(words => {
    if (ment.toLowerCase().includes(words.toLowerCase())) {
      return true;
    }
  });

it giving true because "random" contains "ran" but I want true only if matches whole string not characters.

• 3 Use === instead of .includes? – CertainPerformance Commented Mar 5, 2019 at 8:42

You can do this:

const mentArray = {
    "words": [ "xyz", "abc", "random", "sample" ] 
};

const ment = "hello world ran";
const mentArr = ment.split(' ');

mentArray.words.find(words => {
    if (mentArr.includes(words.toLowerCase())) {
        return true;
    }
});

var mentArray ={ "words":[ "xyz", "abc", "random", "sample" ] }

 var ment = "hello world random";
 var mentInWords = ment.split(" ");
 var res = mentArray.words.filter(words => {
    let a = _.includes(mentInWords,words.toLowerCase())
        if (a) {
          return true;
        }else{
          return false;
      }
 });

 console.log(res)

var mentArray ={ "words":[ "xyz", "abc", "random", "sample" ] };
var ment = "hello xyz";
var mentInWords = ment.split(" ");
 var res = mentArray.words.filter(words => {
   for(var i = 0; i <= mentInWords.length; i++){
    var a = (mentInWords[i] == words.toLowerCase());
        if (a) {
          return true;
        }
   }
 });

 console.log(res)

1) Split the string "ment" into array of words

2) For each word from ment, try to find it in you "words" array. You can use something like your parison but you need to pare with === instead of includes, of course.

mentArray.words.some( word => ~ment.split(" ").indexOf(word))
