React Js convert string to Key-Value Object

React Js convert string to Key-Value Object:In Reactjs, converting a string to a key-value object typically involves parsing the string and creating an object with key-value pairs. You can achieve this by splitting the string into pairs, typically separated by a delimiter like ":" or "=", and then mapping them into an object. For example, if you have a string "name:John age:30", you can split it and create an object like { name: "John", age: 30 }. This process is often used when working with form data or configuration settings

How can you convert a string representation of key-value pairs into a JavaScript object in Reactjs?

value object, keyValueObject. The useEffect hook is used to perform this conversion when the component mounts. Inside the hook, each string in stringArray is split at the colon (':') character, creating a key-value pair. If both a key and a value exist, they are added to the updatedKeyValueObject. Finally, the keyValueObject state is updated with the updatedKeyValueObject, and the result is displayed in the component's rendering. This code transforms ["name:John", "age:30", "city:New York"] into {"name": "John", "age": "30", "city": "New York"}.

React Js convert Array of string to Key-Value Object Example

  <script type="text/babel">
    const { useState, useEffect } = React;
    function App() {
      const stringArray = ["name:John", "age:30", "city:New York"];
      const [keyValueObject, setKeyValueObject] = useState({});

      useEffect(() => {
        const updatedKeyValueObject = {};

        stringArray.forEach(item => {
          const [key, value] = item.split(':');
          if (key && value) {
            updatedKeyValueObject[key] = value;
          }
        });

        setKeyValueObject(updatedKeyValueObject);
      }, []);

      return (
        <div className='container'>
          <h3 className='title'>React Js convert string to Key-Value Object</h3>
          <p className='text'>Array of String{JSON.stringify(stringArray)}</p>
          <pre className='code'>Key Pair Object : {JSON.stringify(keyValueObject, null, 2)}</pre>
        </div>

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

Converting Comma-Separated Key-Value Pairs to an Object in ReactJS Using useState and Object.fromEntries

This ReactJS code takes a string containing key-value pairs separated by commas and converts it into a key-value object. It uses the useState hook to manage the input string and splits it into pairs. Then, it maps each pair to split it into key and value components. Finally, it creates a key-value object using Object.fromEntries and displays the original string and the resulting object in a React component.
