How to check array if it contains a string with same text?

Question

How do you check an array if a string contains the same text? Example, I have cards array that I declare and I want to find how many have the same string like clubs in my array. I tried using includes using jquery and it returns a boolean function true or false. What should be done here? Will it possible to use the find method in the array? Please help.

It should alert that an array has 3 strings that has the same value like clubs.

$(document).ready(function() {

var cards = ["ace_of_clubs.png","2_of_clubs.png","3_of_clubs.png","ace_of_hearts.png"];

var f_string = cards.includes("clubs");
alert(f_string);

});

You can use array#filter with string#includes to check for substring in your array of string.

var cards = ["ace_of_clubs.png","2_of_clubs.png","3_of_clubs.png","ace_of_hearts.png"],
    f_string = cards.filter(card => card.includes("clubs"));
console.log(f_string);

ES5 Code

var cards = ["ace_of_clubs.png", "2_of_clubs.png", "3_of_clubs.png", "ace_of_hearts.png"],
    f_string = cards.filter(function (card) {
    return card.includes("clubs");
});
console.log(f_string);

How do I use f_string variable in an if condition sir @Hassan Imam do I freely use this if(f_string) to check how many string that has a substring of clubs?

In case you want to check for length, use f_string.length in your if condition.
