In the JS community, it means a library that can run client-side (in the browser) or server-side (in NodeJS).

I'm not sure this is the issue you are referencing, but you can use multi-stage Docker image builds to avoid bundling the JDK in the final Docker image: FROM openjdk:jdk AS build COPY . . RUN mvn package FROM openjdk:jre

If I have this: <div v-for="item in items"> <span>...</span> </div> The refactoring tools must know that the "items" inside the "v-for" refers to a property of the

If your project grows big, you will at some point need to use a state management library like VueX which has similar concepts than Redux, so I'm not sure this argument holds. My biggest problem with Vue is the template syntax. Since JS

Your guide is the first thing I open in my browser every time I need to code an algorithm in a hexagonal space. Thanks a lot for the amazing work!

Can someone explain to me why someone would choose Redux over something like MobX ? I feel like implements an action for each modification of state (or group of modifications) requires a lot of boilerplate code. In MobX, you treat your data

During the learning phase of the SVM, you try to find an hyperplane that maximizes the margin. The decision function of an SVM can be written as: f(x) = sign(sum alpha_sv y_sv k(x, sv)) Where sum represents the sum over all support v

In the decision function of an SVM, you compute the scalar products of the support vectors (points that are on the margin of your hyperplane, or more precisely, the points that constrain your hyperplane) and your new sample point: x· sv

I don't know if you are more familiar with matrix notation phi(x) = [x1, x2, x1² + x2²] phi(x)· phi(y) = [x1, x2, x1² + x2²]*[y1, y2, y1² + y2²] phi(x)· phi(y) = x1 y1 + x2 y2 + (x1² + x2²)(y1² + y²)

Machine learning (and more specifically here, supervised learning) is about predicting a specific attribute of a new sample, based on the attributes of the samples that you've acquired. For example, if you have access to the database

Typescript with React is necessary for me. I feel like it highly increases my productivity when coding, and it makes it easy to refactor the code. Plus you can do some cool things like Component inheritance. I've never tried Flow, but

You can use Rice's theorem[1], which is a generalized version of the Halting problem. I don't believe this proves that programming can't be automated, though. Humans too aren't able to prove completely that what they wri

React managed to make HTML "statically typed". If I make a typo in the name of a component or the name of an attribute used in a HTML tag property, Typescript will catch it. Since Vue & Angular uses template strings, TS can&#x

Maybe it is me, but I feel like mapped types and keyof are terrible features, and using them would be a sign of a bad design/architecture. In general, I don't think using a string that represents a static symbol (such as the name

by Longwelwind 10y ago
Why not ? I only see advantages for static typing for a small cost of time: you prevent most of Type Error from happening, you get automatic auto-completion, refactoring errors are easier to catch and feel safer. Either way, you need to spe

Thanks, I didn't know that Ember did more than just fetching the value. About time wasted, I feel like in the long run, you gain more time by writing statically analyzable code. If you make a typo in the string, you would have to build

Over-reliance on strings is a pattern that I've seen a lot in the Javascript environment. For example: var arr = [{ value: 'a' }, { value: 'a' }, { value: 'b' }, { value: 'b' }]; arr.uniqBy

I'm not sure it should be considered as a reason for anything. The most important point of the article, imo, is: If a function is only called from a single place, consider inlining it. You should consider inlining your function,

I believe "module" in classic Javascript already corresponds to a "self-contained" Javascript file.
