Syntax error Create new array without impacting values from old array in JavaScript?

Create new array without impacting values from old array in JavaScript?

Let’s say the following is our current array −

var listOfNames=["John","Mike","Sam","Carol"];

Use JSON.parse(JSON.stringify()) to create new array and set values from the old array above.

Example

function createNewArray(listOfNames) {
   return JSON.parse(JSON.stringify(listOfNames));
}
var listOfNames=["John","Mike","Sam","Carol"];
var namesArray = listOfNames.slice();
console.log("The new Array=");
console.log(namesArray);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo111.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo111.js
The new Array=
[ 'John', 'Mike', 'Sam', 'Carol' ]
