slice()

Another method to create a shallow copy is the slice() method. When called without arguments, slice() returns a shallow copy of the entire array. Here’s how it works

let originalArray = [1, 2, 3];
let copyArray = originalArray.slice();
 
console.log(copyArray); // [1, 2, 3]
console.log(copyArray === originalArray); // false

In this case, originalArray.slice() creates a new array that is a shallow copy of originalArray. Again, the copyArray contains the same elements but is a different array object.
