At the Developer Productivity Engineering Summit! Loving the vibe already 😃 #dpesummit
Sometimes, it may be better to give tasks to less experienced team members, who has not yet reached the peak of their proficiency and is still motivated to learn, rather than someone who has started their journey down the slope of boredom. #softwareengineering #management
For these hard-to-automate tasks, putting the most experienced/qualified person on the task may not always yield the most efficient results. The role of the manager, then, is to find the right balance between learning and performing for each team member.
If you're a team lead or engineering manager, don't always assign tasks to the most experienced/qualified person. #softwareengineering #softwaremanagement #management #techlead
Note, however, that `test.concurrent` is experimental, and does not support `beforeEach`/`beforeAll`/`afterEach`/`afterAll` (github.com/facebook/jest/…).
Test cases within each file runs in sequence. You can use `test.concurrent` (jestjs.io/docs/api#testc…) to run tests concurrently within the same file. You can also use the `maxConcurrency` (jestjs.io/docs/configura…) config to limit the number of concurrent tests at any one time.
@fbjest runs tests in parallel right? Well...yes and no. #javascript #TypeScript #qualityassurance #Softwaretesting #webdevelopment
There's also a helpful `Number.isSafeInteger(number)` (tc39.es/ecma262/#sec-n…) method that will check whether a number is in that range. In summary, you *can* safely store integer *values* as long as they are between `Number.MIN_SAFE_INTEGER` and `Number.MAX_SAFE_INTEGER`.
...that's why the ECMAScript standard have given names to these numbers as the constants `Number.MIN_SAFE_INTEGER` (tc39.es/ecma262/#sec-n…) and `Number.MAX_SAFE_INTEGER` (tc39.es/ecma262/#sec-n…), respectively.
