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”).

They allow you to examine the current code state: I know html-inspector had a way to write your own rules, but it’s getting a bit long in the tooth so I don’t know if there is success to be found there or not.Please open the informational dropdowns to the right (labeled with arrows). But unfortunately, Stylelint is for linting CSS and it sounds like the main issue here is HTML. The first thing I thought of was a custom Stylelint rules that would look for selectors that your team knows to be deprecated and warn you. For example, one of us might open a HTML file and see an element with a class name of deprecated-selector, our goal is to have our IDE literally mark it as a linting error and say like “This is a deprecated selector, use.

I work on a development team working on an old project, and we want to get of rid many of our oldest and buggiest CSS selectors. I found this all related to an interesting question that came my way: It’s nothing like if (('old')) throw('Deprecated selector.') or something easy like that. You gotta know you way around an Abstract Syntax Tree. But fair warning, I found the process for writing custom rules in both of those pretty difficult. I was interested as a user of both ESLint and Stylelint in my main codebase.

“Custom Stylelint Rules - Writing Your First one” by Omri Lavi.“How to write a custom ESLint rule” by Benedict Quinn.I thought about it as two different posts about custom linting crossed my desk recently: Protecting your code with more code that you write is where I wanted to go with this, not with traditional tests, but with custom linting rules. They are about making sure your code does what it is meant to do, and as such, deliver a hell of a lot of value. Tests are the big player here, which can even be set up to run as you code. Then there is tooling that protects your code via more code that you have to write. Webhint bundles a bunch of those together and is probably worth a look. There are whole suites of tools you can put in that “as-you-are-coding” bucket, like accessibility linting, compatibility linting, security linting, etc. I think of Prettier here, a code formatter that keeps your code in shape, usually right as you are coding. Some of this tooling is so easy to implement, it is often done right up-front. Avoid premature optimization but avoid, uh, postmature optimization.

I’m not sure how to articulate when, but it’s somewhere after the project has proven to be something long-term and rough edges are starting to show, and before things feel like a complete mess. There comes a time on a project when it’s worth investing in tooling to protect the codebase.
