# JavaScript: Remove Duplicates From Sorted Array in Place

Today, we will work on Remove Duplicates from Sorted Array algorithm from LeetCode’s Top Interview Questions List:Given a sorted array nums, remove the duplicates in-place such that each element appears only once and returns the new length.

Today, we will work on Remove Duplicates from Sorted Array algorithm from LeetCode’s Top Interview Questions List:

Given a sorted array _**_nums_, remove the duplicates _[in-place**](https://en.wikipedia.org/wiki/In-place_algorithm)_ such that each element appears only once and returns the new length._

Do not allocate extra space for another array, you must do this by __modifying the input array _[**_in-place**](https://en.wikipedia.org/wiki/In-place_algorithm)_ with O(1) extra memory._

``````Example 1:

Given nums = [1,1,2],
Your function should return length = 2, with the first two elements of nums being 1 and 2 respectively.
It doesn't matter what you leave beyond the returned length.
Example 2:
Given nums = [0,0,1,1,1,2,2,3,3,4],
Your function should return length = 5, with the first five elements of nums being modified to 0, 1, 2, 3, and 4 respectively.
It doesn't matter what values are set beyond the returned length.``````

## Learn Arrays And Array Methods in JavaScript

In JavaScript, an array is a data structure that contains list of elements which store multiple values in a single variable. The strength of JavaScript arrays lies in the array methods. Array methods are functions built-in to JavaScript that we can apply to our arrays — Each method has a unique function that performs a change or calculation to our array and saves us from writing common functions from scratch. In this video we are going to learn arrays and array methods like sort(), reverse(), join(), split(), pop(), push(), shift(), unshift(), toString(), delete array, etc.......

To create a 2D array in JavaScript, we have to create an array of array. To declare a 2D array, use the same syntax as declaring a 1D array.

## Algorithms With JavaScript: Median of Two Sorted Arrays

Solving algorithms problems is crucial for building a solid computer science foundation for software engineers. Today we will try to solve the Median of Two Sorted Arrays.

## Increase Performance of React Applications Via Array JavaScript Methods

Increase Performance of React Applications Via Array JavaScript Methods. We will create a simple event management application in the react to add, update, and delete an event.

## Fill and Filter in Array in JavaScript

By the word Array methods, I mean the inbuilt array functions, which might be helpful for us in so many ways. So why not just explore and make use of them, to boost our productivity. Let’s see them together one by one with some amazing examples.
