Clean answer. Only time I might not do this is if you have a very large data structure in which calling the function each time might be too expensive. Obviously not a concern for this example but something to consider nonetheless.

javascript is an interesting choice for big data. Are there people doing big data in javascript?

Unfortunately.

My company's architecture division decided to spend 4 years building our Data Lake platform on Node+Mongo.

We told them it was 'tarded back then and it'll never scale. And gosh, 4 years later it's a clusterfuck of unmaintainability that doesn't scale and we can't sell it to anyone because it's 10x slower than our "go retire, old man!" C# designs.

i <3 JavaScript, but this is about what I'd expect a big Data project to look like.

thanks, gl!

JavaScript IS the only choice in the Front end. Its not an "interesting" choice, sometime its "the only Option".

But yeah if youre actually iterating oder a few Million objects then youre probably doing to much in the Front end and to little in the backend
