Accessing the Last Logged Value in Chrome Console
Whenever you are working on debugging or experimenting with code in the Chrome Developer Tools console, you might find it handy to access the last logged value that you displayed. This can be quite useful in scenarios where you need to work with the previously displayed value without repeating the same command or assigning it to a variable manually. In this article, you will learn how to easily access the last logged value in the Chrome console, saving you time and effort in your coding journey.
Chrome Developer Tools provide a nifty feature that allows you to reference the last logged value using an underscore symbol (_). When you log a value using console.log(), the value is stored internally, and you can quickly access it by simply typing an underscore (_) in the console and hitting Enter.
For instance, if you logged a value like this:
console.log('Hello, world!');To access the value 'Hello, world!' again without typing the console.log command, you can do so by just typing:
_After pressing Enter, you will see the last logged value displayed in the console. This feature can significantly improve your workflow by eliminating the need to re-type or execute commands repeatedly.
Moreover, the underscore (_) referencing the last logged value is not limited to console.log(). You can use this approach with other console methods like console.dir(), console.warn(), or even with the returned values of functions you executed in the console.
It's important to note that the underscore (_) represents the value of the most recent expression evaluated in the console. If you want to reference an older value, you can still do so using multiple underscores. For example, typing two underscores (__), three underscores (___), and so on, allows you to reference the second-to-last, third-to-last, and older logged values, respectively.
In addition to accessing the last logged value using underscores, you can also incorporate this technique within your code or scripts for more efficient debugging and exploration. By referencing the last value logged in your script, you can dynamically work with the data without hardcoding it.
In conclusion, being able to access the last logged value in the Chrome Developer Tools console using the underscore symbol (_) is a valuable technique that can enhance your productivity and streamline your coding experience. Remember to leverage this feature to your advantage and save time while debugging and experimenting with code. Happy coding!
