Pluralize data according to its count using Vue Filters

  • Last Updated : 31 Mar, 2021

Vue is a progressive framework for building user interfaces. The core library is focused on the view layer only and is easy to pick up and integrate with other libraries. Vue is also perfectly capable of powering sophisticated Single-Page Applications in combination with modern tooling and supporting libraries.

Filters are a functionality provided by Vue components that let you apply formatting and transformations to any part of your template dynamic data. The filter property of the component is an object. A single filter is a function that accepts a value and returns another value. The returned value is the one that’s actually printed in the Vue.js template. 

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

For pluralizing data according to its count, we have to write the filter logic to show data in singular and plural forms. We simply check if the given count is equal to 1 and depending on the result decide to display the singular or plural forms.

Example:



index.html




<html>
<head>
  <script src=
  </script>
</head>
<body>
  <h1 style="color: green;">GeeksforGeeks</h1>
  <div id='parent'>
    <p><strong>No. of item: </strong
      {{ c1 | pluralize('Book','Books') }}
    </p>
  
    <p><strong>No. of item: </strong
      {{ c2 | pluralize('Chair','Chairs') }}
    </p>
  
    <p><strong>No. of item: </strong>
      {{ c3 | pluralize('Potato Fry','Potato Fries') }}
    </p>
  
    <p><strong>No. of item: </strong>
      {{ c4 | pluralize('Ice Cream','Ice Creams') }}
    </p>
  
    <p><strong>No. of item: </strong>
      {{ c5 | pluralize('Mobile','Mobiles') }}
    </p>
  
  </div>
  <script src='app.js'></script>
</body>
</html>

app.js




const parent = new Vue({
  el: "#parent",
  data: {
    c1: 1,
    c2: 5,
    c3: 100,
    c4: 10,
    c5: -9,
  },
  
  filters: {
    pluralize: function (count, sing, plur) {
  
      // Decide to pluralize based
      // on the count
      if (count == 1) {
        return count + ` ${sing}`;
      } else if (count > 1) {
        return count + ` ${plur}`;
      } else {
        return "Please pass valid count of data";
      }
    },
  },
});
