Tutorial: Intro to Respond. Before the Tutorial is started by us

Inspecting the Starter Code

If you’re going to operate on the guide in your web web web web browser, available this code in a tab that is new Starter Code. If you’re going to exert effort in the tutorial locally, alternatively open src/index.js in any project folder (you have previously moved this file through the setup).

This Starter Code could be the base of just just what we’re building. We’ve provided the CSS styling so you just need to concentrate on learning respond and programming the tic-tac-toe game.

By inspecting the rule, you’ll observe that we now have three React elements:

  • Square
  • Board

The Square component renders an individual additionally the Board renders 9 squares. The overall game component renders a board with placeholder values which we’ll modify later on. You can find presently no interactive elements.
