How can I pass data from Flask to JavaScript in a template?
...
Yes, you could, and in some architectures (esp. SPAs) this is the proper way to do things, but bear in mind that there are several disadvantages to doing this versus baking the data into the page when you serve it: 1. it's slower, 2. it requires slightly more code eve...
Best Practice: Initialize JUnit class fields in setUp() or at declaration?
...uld fail, in which case use @Before, to catch failures.
