Javascript Convert Array to Set - React Js | Vue Js

Javascript Convert Array to Set - React Js | Vue Js:In JavaScript, converting an array to a Set can be done using the Set object. In frameworks like React.js or Vue.js, you can achieve this by creating a new Set and passing the array as an argument. By doing so, duplicate elements will be automatically removed, and only the unique values will be stored in the Set. This can be useful when you want to eliminate duplicates from an array and work with a collection of distinct values.

How can you convert an array to a set in JavaScript?

This JavaScript code converts an array to a set. It defines a function called convertArrayToSet() that is triggered when the page loads. Inside the function, an array with duplicate elements is created. The original array is displayed on the webpage. Then, a new Set is created from the array, eliminating duplicates. The Set is then converted back to an array using Array.from(). The converted array is displayed on the webpage.

Javascript Convert Array to Set

<body>
  <h3>Javascript Convert Array to Set</h3>
  <div id="originalArray"></div>
  <div id="convertedArray"></div>
</body>
<script>
    // JavaScript code
    function convertArrayToSet() {
      const array = ['a', 'a', 3, 4, 4, 5, 5];
      
      // Display the original array in the webpage
      document.getElementById('originalArray').innerHTML = "Original Array: " + array;
      
      // Create a new Set from the array
      const set = new Set(array);
      
      // Convert set to an array
      const convertedArray = Array.from(set);
      
      // Display the converted array in the webpage
      document.getElementById('convertedArray').innerHTML = "Converted Array: " + convertedArray;
    }

    // Trigger the conversion when the page loads
    window.addEventListener('load', convertArrayToSet);

How can you convert an array to a set in Reactjs?

This React.js code snippet converts an array to a set using the useState and useEffect hooks. Initially, the array [1, 2, 3, 3, 4, 5, 5, "a", "b", "c", "c"] is stored in the array state variable. The setSet function from the useState hook is used to initialize an empty set.

Inside the useEffect hook, the array is converted to a set using new Set(array), and then the setSet function is called to update the set state variable with the converted set. The converted set is displayed in the rendered JSX using Array.from(set).

React Js Convert Array to Set - Javascript Example

   <script type="text/babel">
      const { useEffect, useState } = React;
      const App = () => {
        const [array] = useState([1, 2, 3, 3, 4, 5, 5, "a", "b", "c", "c"]);
        const [set, setSet] = useState(new Set());

        useEffect(() => {
          const convertedSet = new Set(array);
          setSet(convertedSet);
        }, [array]);

        return (

            <h2>Original Array:</h2>
            <p>{JSON.stringify(array)}</p>
            <h2>Converted Set:</h2>
            <p>{JSON.stringify(Array.from(set))}</p>
          </div>
        );
      };

      ReactDOM.render(<App />, document.getElementById("app"));

How can I convert an array to a set using Vuejs?

This Vue.js code snippet demonstrates how to convert an array into a set using Vue.js. The initial array is defined in the data section, and the converted set is stored in the setArray variable. The mounted hook calls the convertArrayToSet method, which converts the array to a set using Array.from(new Set(this.array)). The resulting set is assigned to setArray and can be displayed in the HTML template using the double curly brace syntax.

            setArray: [],
          };
        },
        mounted() {
          this.convertArrayToSet();
        },
        methods: {
          convertArrayToSet() {
            this.setArray = Array.from(new Set(this.array));
          },
        },
      });
