date-fns VS mathjs

// Prevent the date to lose the milliseconds when passed to new Date() in IE10 return new (argument.constructor as GenericDateConstructor)( +argument, ); // Source: https://github.com/date-fns/date-fns/blob/5c1adb5369805ff552737bf8017dbe07f559b0c6/src/toDate/index.ts#L46

For the longest time working with dates in JavaScript was a huge pain. That’s why libraries such as moment.js or date-fns are so popular. A lot of times I’d reach for these libraries when working with relative time formatting, but since late last year we’ve had pretty great browser support for the RelativeTimeFormat() method. In my mind, relative dates are just more visually appealing, especially for working with dates internationally. Dates like "5 days ago" or "in 2 months" are far more intuitive for users than 12/12/2023, or 03/11/2027. Folks in the US will see that as March 11, 2027, whereas the rest of the world will see that as November 03, 2027. What a nightmare.

8. Date-fns - Simplifying Time Manipulation ⏳

I work with date-fns and date-fns-tz

In past i used Moment, but I read that we should avoid to use it for future projects. I read someone suggested to use Datejs, but it doesn't seems to be updated, last time was 8 years ago. Currently I'm thinking to use Luxon but I someone suggest Date-fns also.

date-fns : Date handling

Thanks! I used date-fns for the calendar

I've used this before and I like it more

The default date constructor does a really great job at parsing in most cases and things like addition/subtraction along with many other common operations are usually just simple math. If you really want to abstract that use date-fns where most date operations are tree shakable to be left with just a few lines of code.

The Math blocks are powered by Math.js (https://mathjs.org/).

math.js is a comprehensive JavaScript library that offers support for working with matrices and multidimensional arrays. It contains a huge array of mathematical functions in addition to array operations, making it suitable for a wide range of mathematical activities.

ii) Third-Party Libraries There are various libraries like math.js, decimal.js, big.js that solve the problem. Each library functions according to its documentation. This approach is comparatively better.

mathjs integration. Supports numbers, big numbers, complex numbers, fractions, units, strings, arrays, and matrices. Is compatible with JavaScript’s built-in Math library. Contains a flexible expression parser. Does symbolic computation. Comes with a large set of built-in functions and constants.

hey, this looks interesting. there is library, mathjs , that is providing pretty printing , which I'm looking for.

It's because it's not supported out of the box by the mathjs library I'm using: https://mathjs.org/

I agree that this would be nice.

Ha, yes, I was being nosy. It was quite easy to spot as it's the only XHR/Fetch request.

I was intrigued what you had used to build it, and if you had built your own solver (which you have), and what editor you used (Code Mirror) so went looking at the code. Interesting to see you left the source maps for production, made it easy for my sleuthing...

I experimented with a similar idea last year, but used ProseMirror/TipTap as the editor to enable rich text editing, and the MathJS (https://mathjs.org) solver. I also combined it with PouchDB and Yjs for offline editing and syncing between devices. Never finished it though, you have kept your nice and simple!

This is nice but I believe something much better can be achieved using JavaScript, in particular math.js.

I also found this math input library: http://mathquill.com/ , and https://mathjs.org/ seems to contain code for solving math problems.

What about math.js? It has an expression parser that looks pretty nice.
