i can do the same with document.write(a+b); can you tell the difference between log.console and document.write

@nextrie

2 жыл бұрын

Hey, in a nutshell, the document.write() method writes content to a (HTML) document. But careful, because it will clear any previous/existing HTML on the loaded document. On the other hand, the console.log() methods writes content/data to your browser's console and is useful for debugging purposes. You may want to watch the tutorial I made on document.write(), in this playlist: kzread.info/dash/bejne/f41mupRpY6nagqw.html

Hey Dziri, there may be tools for that, but many websites minify their scripts anyway (partly for performance reasons), so they gets purposely obfuscated and hard to understand. However, if you have access to a site's source scripts, then you can simply add a breakpoint in the script where you wish, in the browser console.

Hey Mike, I guess it depends on your auto-completion settings, whether you are using an extension to autocorrect what you write in the editor, and also your VS Code version. But I guess you can look into how to disable auto-completion to avoid that and see if it resolves the issue.

What will be output of console.log("test" && "book")? It is printing only book !! Why?

@nextrie

3 жыл бұрын

Hey Praveen, in your example, both "test" and "book" are string literals, and they are not undefined. So it's as if your console logging statement is verifying two values that both evaluate to TRUE. In this case, using the logical AND operator (&&) will cause the function to log the last TRUE value (which is "book"). On the contrary, if you were to use the OR operator (||), then you would get the first TRUE value (which would be "test").

Why is expressions between variables used for like can’t we just write the response ex Var name= “john”+”smith”

@nextrie

4 жыл бұрын

Hey yes, your example is a perfectly valid way of declaring and initializing a variable. Just note that because you do not have a space after "john", the string values will be concatenated as one single word ("johnsmith").

NexRank that the point why not directly write “johnsmith” instead of “john”+”smith” or “john smith” instead of “john “+”smith”

@nextrie

4 жыл бұрын

​@@wellsleep549 Ah, I get you. Well no. Here's my (long) explanation: In your example, you are storing a string literal. You are the one providing the value to the variable, and you already know what it is. So you should in fact write it directly like this: "john smith" There's no need for concatenation with the + sign here. However, in the real world, web applications usually work with a lot of dynamic values. They receive data from user input (e.g. forms), or APIs, etc. Usually, you would capture these values in variables to use them later. To clarify, let's say you have a form on an HTML page with two text fields. The first one is for the user to input their first name, and the second one is for their last name. Upon submission of the form, you would capture the input from these two text fields and store them into two variables. I'll call these variables fname and lname. Now, let's say you want to display a greeting that includes the user's full name. The greeting is supposed to read: "Hello, John Smith!". That's when concatenation is useful. You can only access the user's first name and last name via the two variables in which you stored the input. So the string for your greeting to the user would look like this: "Hello, " + fname + " " + lname + "!" If another user now submits the form with a different first name and last name, then the greeting will dynamically reflect their details. But your script won't change. The values are still being stored in the fname and lname variables. That's a good point for concatenation. Personally, I prefer to use template literals instead of that classic style of concatenation. I recommend you check out my two videos on that to understand more about concatenation below. Hope this helps! Concatenation: kzread.info/dash/bejne/f41mupRpY6nagqw.html Template literals: kzread.info/dash/bejne/k6hrlalyqpetYZc.html

Cannot get anything in console.log in windows 10 chrome.. Please help

@nextrie

2 жыл бұрын

Hey Prajwal, using Chrome with/without Windows 10 will not stop you from using console.log(), as the latter is a method directly from JavaScript (and not implemented by the OS). Try the following steps: - Open a fresh Chrome window - Press (at the same time) CTRL + SHIFT + I (the last key is a capital i, not an L) - In the DevTools window that appears, click on the Console tab - In the Console tab, type this: console.log("Testing") - Press the Enter key - You will see "Testing" printed back to you on the next line in DevTools So, if you have some JavaScript file or code that fails to print anything in the console, then it could be that you're looking at the logs from the wrong browser tab/wrong Chrome window, or that your server isn't running, or that your code has a bug preventing your log statements from being executed in the first place.
