push()

Add to the end of an array

Goal

Learn to add new elements to the end of an array using push().

Explanation

  • push() adds a new element to the end of an array.
  • You can add strings, numbers, and other values.
  • The array changes after push() is called.
  • The new element becomes the last item in the list.
  • push() is one of the most popular array methods.

Analogy

Imagine a line of people. push() adds a new person at the very end of the line.

Code

const fruits = [
  "Apple",
  "Banana"
];

fruits.push("Orange");

console.log(fruits);

Result: ["Apple", "Banana", "Orange"]

Common mistake

Beginners sometimes expect push() to add an element at the beginning. In fact, it always adds the element at the end.

Remember

  • push() adds an element to the end of an array.
  • push() changes the original array.
  • The new element becomes the last one.
