When one with typeof operator one gets type object it falls into somewhat wast category... In practice you might need to narrow it down to what sort of 'object' it actually is and one way to do it is to use object constructor name to get what flavour of object it actually is: Object.prototype.toSt...

Instead of this (unfortunately too often seen in the real code) "masterpiece": function isEven(n) { return n % 2 == 0; } function isOdd(n) { if (isEven(n)) { return false; } else { return true; } } You can do the parity check much more effecti...

class Monad m where return :: a -> m a (>>=) :: m a -> (a -> m b) -> m b The most important function for dealing with monads is the bind operator >>=: (>>=) :: m a -> (a -> m b) -> m b Think of m a as "an action with an a result". ...

Static analysis is the technique in which on checks the code for patterns linked to known bugs. Using this technique is less time consuming than a code review, though, its checks are only limited to those programmed in the tool. Checks can include the incorrect semi-colon behind the if-statement (i...

In this example we use Tensorflow to count to 10. Yes this is total overkill, but it is a nice example to show an absolute minimal setup needed to use Tensorflow import tensorflow as tf # create a variable, refer to it as 'state' and set it to 0 state = tf.Variable(0) # set one to a constan...

This is where safe-stack comes into play. Instead of using a single stack for your threads, it will use two: A safe stack and a dan...

Let's say we have a component that should only be displayed if the user is logged in. So we create a HOC that checks for the authentication on each render(): AuthenticatedComponent.js import React from "react"; export function requireAuthentication(Component) { return class Auth...
