✐ Examples
1 Using Array.of() method to create an empty array
In JavaScript, we can use the Array.of() method to create a new empty array.
For example,
- We use the Array.of() method with no arguments to create a new empty array.
- The result is stored in the variable emptyArray.
- We log emptyArray to the console using console.log() method to see the created array.
JavaScript Program
const emptyArray = Array.of();
console.log(emptyArray);Output
[]
2 Using Array.of() method to create an array with one element
We can use the Array.of() method to create a new array with one element.
For example,
- We use the Array.of() method with one argument, 1, to create a new array with one element.
- The result is stored in the variable singleElementArray.
- We log singleElementArray to the console using console.log() method to see the created array.
JavaScript Program
const singleElementArray = Array.of(1);
console.log(singleElementArray);Output
[1]
3 Using Array.of() method to create an array with multiple elements
We can use the Array.of() method to create a new array with multiple elements.
For example,
- We use the Array.of() method with multiple arguments, 1, 2, and 3, to create a new array with three elements.
- The result is stored in the variable multipleElementsArray.
- We log multipleElementsArray to the console using console.log() method to see the created array.
JavaScript Program
const multipleElementsArray = Array.of(1, 2, 3);
console.log(multipleElementsArray);Output
[1, 2, 3]
