How to use a Temporary Variable In Javascript

swapping values between two arrays of objects using a temporary variable involves the following steps:

Create a temporary variable to store the value of the array during the swap.
Assign the value of the first array of object to the temporary variable.
Assign the value of the second array of object to the position originally held by the first array of object.
Assign the value stored in the temporary variable to the position held by the second array of object.
Repeat the assignments for each corresponding pair of object in the arrays.
After completing the swap for all object in the arrays, return ‘true’ to indicate that the swapping was successful.

Example: This example shows the implementation of the above-explained approach.

Javascript

function fun(arrayA, arrayB) {

    // Arrays must have the same length
    if (arrayA.length !== arrayB.length) {
        return false;
    }

    for (let i = 0; i < arrayA.length; i++) {
        let tempVariable = arrayA[i];
        arrayA[i] = arrayB[i];
        arrayB[i] = tempVariable;
    }
    // Swapping arrays successful
    return true;
}

let arrayA = [{ name: "geek" },
{ name: "geek3" }];
let arrayB = [{ name: "geek1" },
{ name: "geek7" }];

let result = fun(arrayA, arrayB);
if (result) {
    console.log(arrayA);
    console.log(arrayB);
}
else {
    console.log("The length of an array must be the same");
}

Output

[ { name: 'geek1' }, { name: 'geek7' } ]
[ { name: 'geek' }, { name: 'geek3' } ]

How to Swap Two Array of Objects Values using JavaScript ?

Swapping values between two arrays of objects is a common operation in JavaScript, there are multiple methods to swap values between arrays of objects efficiently. Swapping values between arrays can be useful in scenarios like reordering data, shuffling items, or performing certain algorithms.
