It does work fine in those situations and works just fine as the OP requested, for alert. Many answers here do not address using alert as the OP requested. Anyhow, It is, however, formatted for data transport. This version seems to return a very similar result as toSource().
If you console.log all of the data, you will see that there are many more properties for each user. The first log will print the properties within the user object. The second will identify the object as “user” and print the properties within it. Instead of typing console.log() three times we can include them all.
- The second will identify the object as “user” and print the properties within it.
- But, did you know that there is more to console than just log?
- This version is more like a poly-fil so that you can use it in any environment.
- And to reset this counter, we have to pass the name into countReset.
Thus, it’s easier to simply use a utility library like Lodash, instead of implementing the entire functionality on your own. When you get into your console window, you’ll see your object logged nicely in a form of an expandable tree. There will also be a little preview of what you can find inside. Above you can see the most basic way to log an object – by using console.log(). Don’t get me wrong – it’s completely fine to do it that way, but it has one fundamental flaw – dynamically evaluation. Now, I don’t want to remind you that everything in JS is an object. We’re interested in properly logging an object, which here is just a “simple” key-value structure.
The styles get passed into the second argument of the log. And to reset this counter, we have to pass the name into countReset. This way you can have several counters running at the same time and only reset specific ones. If we were to change isItWorking to true, then the message will not be logged. If the first argument is false, then the message will be logged. We can print messages to the console conditionally with console.assert().
How do I display the output console in HTML?
