JavaScript accesses the contents of a webpage making use of Document Object Model which is created by the browser when a webpage is rendered. JS helps in increasing user engagement on a web page through special effects. It is also used to create web applications across platforms.

A lot of other web applications that are prominent in the market today are coded in JS.

Using the map method, we can map our history of moves to React elements representing buttons on the screen, and display a list of buttons to “jump” to past moves. Finally, we need to move the handleClick method from the Board component to the Game component. We also need to modify handleClick because the Game component’s state is structured differently. Within the Game’s handleClick method, we concatenate new history entries onto history. However, we used slice() to create a new copy of the squares array after every move, and treated it as immutable.

JavaScript is a lightweight, interpreted programming language. It is designed for creating network-centric applications. JavaScript is very easy to implement because it is integrated with HTML.
Keys do not need to be globally unique; they only need to be unique between components and their siblings. Replace this.state.squares with this.props.squares in Board’s renderSquare. Now we need to decide which component should own the history state.
React components can have state by setting this.state in their constructors. This.state should be considered as private to a React component that it’s defined in. Let’s store the current value of the Square in this.state, and change it when the Square is clicked. As a next step, we want the Square component to “remember” that it got clicked, and fill it with an “X” mark. We strongly recommend typing code by hand as you’re working through the tutorial and not using copy/paste. This will help you develop muscle memory and a stronger understanding.

Detecting changes in mutable objects is difficult because they are modified directly. This detection requires the mutable object to be compared to previous copies of itself and the entire object tree to be traversed. The first approach is to mutate the data by directly changing the data’s values. The second approach is to replace the data with a new copy which has the desired changes. Lifting state into a parent component is common when React components are refactored — let’s take this opportunity to try it out.
