1. constructor
The constructor returns the function that created the Array object’s prototype.
Example:
<script>
const countries = [“Pakistan”, “Canada”, “USA”, “China”];
var text = countries.constructor;
// text variable will returns like: function Array() { [native code] }
</script>
2. concat()
The concat() method is used to join (concatenates) two or more arrays and return an array with the joined arrays.
Example:
<script>
const arr1 = [“Jhon”, “Lee”];
const arr2 = [“Emma”, “Tessa”, “Anna”];
const arr3 = arr1.concat(arr2);
// arr3 variable will returns e.g: Jhon,Lee,Emma,Tessa,Anna
</script>
3. valueOf()
The valueOf() method returns the primitive value of an array.
Example:
<script>
const countries = [“Pakistan”, “Canada”, “USA”, “China”];
var myArray = countries.valueOf();
// myArray variable will returns like:Pakistan,Canada,USA,China
</script>
4. unshift()
The unshift() method used for add new items beginning of an array.
Example:
<script>
const countries = [“Pakistan”, “Canada”, “USA”, “China”];
countries.unshift(“UK”,“Dubai”);
// Output will be like: UK,Dubai,Pakistan,Canada,USA,China
</script>
5. splice()
The splice() method is used to add/remove elements from an array.
Example:
<script>
const countries = [“Pakistan”, “Canada”, “USA”, “China”];
countries.splice(2,0,”United States”, “United Kingdom”);
// countries variable will returns like: Pakistan,Canada,United States,United Kingdom,USA,China
</script>
6. toString()
The toString() converts an array to a string, and the result method returns a string with all array values separated by commas.
Example:
<script>
const countries = [“Pakistan”, “Canada”, “USA”, “China”];
var text = countries.toString();
// text variable will returns like: Pakistan,Canada,USA,China
</script>
