How to use Array.prototype.splice() Method In Javascript

Using Object.assign and Spread Operator:

Use the Splice() method to remove element from one array and insert them into another array at specified position (index).
Repeat this splicing operation for each pair of corresponding elelment in the arrays.
After completing the swap for all object in the arrays, return ‘true’ to indicating that the swapping was successful.

Syntax:

arrayA.splice(i, 1, ...arrayB.splice(i, 1, arrayA[i])[0]);

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++) {
        arrayA.splice(i, 1, arrayB.splice(i, 1,
            arrayA[i])[0]);
    }

    // Swapping arrays successful
    return true;
}

let arrayA = [{ name: "Pratik" },
{ name: "Mahesh" }];
let arrayB = [{ name: "Rohit" },
{ name: "Rahul" }];

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

Output

arrayA = [ { name: 'Rohit' }, { name: 'Rahul' } ]
arrayB = [ { name: 'Pratik' }, { name: 'Mahesh' } ]
