Step 2: Pause the code with a breakpointĭevTools lets you pause your code in the middle of its execution, and examine the values of all variables at that moment in time. This is the bug that you're going to fix. Look at the label below the inputs and button.Make sure to open this page in a new tab: OPEN DEMO. Here is the webpage we’ll be working with in this tutorial.You may need to reproduce the bug many times, so try to eliminate any unnecessary steps.įollow along with the instructions below to reproduce the bug that you’re going to fix in this tutorial.

To “reproduce the bug” means to find a series of actions that consistently causes the bug to appear. Reproducing the bug is always the first step to debugging.

This tutorial shows you how to debug one specific issue, but the general workflow you learn is helpful for debugging all types of JavaScript bugs. This workflow is often a much more efficient way to find and fix bugs in your code. This article is all about debugging the correct way! You’ll learn how to use the Chrome Developer Tools to set up breakpoints and step through your code. You may be tempted to randomly use console.log() in an attempt to get your code working correctly. In the next chapter you will learn about relative and absolute references.Ditch console.log debugging once and for all! Learn how to use breakpoints to debug code within the Chrome Developer ToolsĪs a new developer, finding and fixing bugs can be difficult. Google Sheets has pre-built functions, such as SUM. The fill function can be used to continue your formulas upwards, downwards and sidewards. The formula updates the result if you change the value of cells, which is used in the formula. Values used in formulas can be typed directly and by using cells.

It allows us to change values that are used by the formulas, and the calculations remain. Notice that the formulas are doing calculations when we change the value in the cells, and the SUM is updated from 33 to 38. The value in cell B2 was changed from 2 to 7. Let's change a value to see what happens. Iva, Liam and Adora have 33 Pokeballs in total. Great job! You have successfully calculated the SUM using the SUM function. Remember to delete the values that you currently have in E5.

Note: You can navigate to the cells with your keyboard arrows instead of right clicking them. You will learn more about functions in a later chapter. The SUM function is one of the most used ones.

Google Sheets has many pre-made functions available for you to use. The total is called SUM in Google Sheets.

Let's see how many Pokeballs Iva, Liam and Adora have in total. Now we have counted the Pokeballs for all the trainers Iva( 6), Liam( 12) and Adora( 15). That is cool, right? The fill function continued the calculation that you used for Iva and was able to understand that you wanted to count the cells in the next rows as well. Lets use the fill function to continue the formula, step by step: Now, let's help Liam and Adora with counting theirs.ĭo you remember the fill function that we learned about earlier? It can be used to continue calculations sidewards, downwards and upwards. The values in row 2 B2(2), C2(3), D2(1) belong to her.ĭid you get the value E2(6)? Good job! You have helped Iva to count her Pokeballs. In this example you should focus on the trainers and their Pokeballs, which have three different types: Pokeball, Great ball and Ultra ball. Note: It is important to practice reading data to understand its context.
