Simple Setup - Vue Linting in VS Code

Jun 17, 2020 by Lane Wagner

I’m a gopher by nature, so I expect consistent styling and linting in my codebases. More importantly, I don’t like to think about styling. I like to type haphazardly and then have my editor apply styles automatically on save (ctrl+s, cmd+s). If you are the same way, hopefully, this will help you in your next Vue.js project.

There are many ways to traverse an array in Javascript. In this benchmark, we will look at five different ways and the pros and cons of each. Keep in mind that these benchmarks were run in a Chrome browser on Codepen.io. Results will vary by browser/interpreter.

How to Recursively Traverse JSON Objects

Sep 22, 2019 by Lane Wagner

I’ve found that it’s pretty rare that I need recursion in application code, but every once in a while I need to write a function that operates on a tree of unknown depth, such as a JSON object, and that’s often best solved recursively. Even though recursion is rare, it is important to recognize when a problem is best solved recursively so that we can implement a good solution when the time comes.
