That’s good if we’re not interested to see what happens inside the function call. The execution is then paused immediately after that function call.
If we compare them, the “Step” command goes into a nested function call and pauses the execution at its first line, while “Step over” executes the nested function call invisibly to us, skipping the function internals. Similar to the previous “Step” command, but behaves differently if the next statement is a function call (not a built-in, like alert, but a function of our own). – “Step over”: run the next command, but don’t go into a function, hotkey F10. If we click it now, alert will be shown.Ĭlicking this again and again will step through all script statements one by one. – “Step”: run the next command, hotkey F9. Take a look at the “Call Stack” at the right.
The execution has resumed, reached another breakpoint inside say() and paused there. Here’s what we can see after a click on it: If there are no additional breakpoints, then the execution just continues and the debugger loses control. – “Resume”: continue the execution, hotkey F8. There are buttons for it at the top of the right panel. There’s also this keyword there that we didn’t study yet, but we’ll do that soon. Global has global variables (out of any functions). You can also see their values highlighted right over the source. “anonymous”), the debugger jumps to the corresponding code, and all its variables can be examined as well. The debugger will show its value, automatically recalculating it in the process of execution.Ĭall Stack – shows the nested calls chain.Īt the current moment the debugger is inside hello() call, called by a script in index.html (no function there, so it’s called “anonymous”). You can click the plus + and input an expression. Watch – shows current values for any expressions.
They allow you to examine the current code state:
Doing so will make Chrome download PDF files instead of opening them.Please open the informational dropdowns to the right (labeled with arrows). Fortunately, Google does allow users to disable the built-in PDF reader in Chrome. Moreover, even if you only had to view the PDF file, Chrome’s built-in PDF reader doesn’t offer features that you might find in third-party dedicated PDF reader software.
Bu not everyone will want to install another browser just to download PDF files. I simply copy and paste the link in Firefox and download the file. I, for some reason, also have Mozilla Firefox installed on all of my PCs alongside Chrome. While the ability to directly view a PDF file without having to download it really helpful, sometimes it’s not, and quite the opposite. There isn’t even a download button you can click anywhere to download that PDF file. At no point does it ask whether you want to download it instead. If you dry to click on the link to a PDF file on Chrome, instead of downloading it, Chrome simply opens it. What if you do want to download PDF files on Chrome though? This means Chrome users can directly open PDF files inside the browser rather than having to download it first. Google Chrome has the support for PDF files built-in.
Those that don’t, manage this via extensions or add-ons. To put this in perspective, Mozilla Firefox, the second in line only has a meager 11.44% market share. Most modern web browsers these days arrive with support for PDF files in-built. Google Chrome was recently declared as the most popular desktop browser with 66.87% of the market share.
