(host = Observer.onnext (host)). Then (_ = = observer.oncompleted ()) . catch (Err = Observer.onerror (Err) })}var tasks = R.range (2, 254). Map (I-= Ping (' 192.168.50.${i} ')) Rx.observable . Merge (... tasks) . Subscribe ( host = Console.log (' Pong: ${host} '), err = console.error (err) )DescriptionThe code is simple enough, and it's worth explaining: The merge-merged operation flow is a sequence of operations that ping the IP in the 192.168.50.2-254

.x version, Lodash provides a "functional development" model for developers who prefer functional programming.If you are familiar with functional programming, you can look at Ramda. If you decide to use this library, you may need to refer to some Lodash functions.FetchMany React-based applications are no longer using jQuery. Unless you are maintaining a stale pro

Well, you just need to know that functional programming is worse than object-oriented programming, and in 2016 we were pointing to functional programming.

that the original program can run normally, suddenly become unable to work or a pile of bugs. NPM is also very sensitive to the order in which packages are introduced, such as executing the following command in an empty project NPM init-y npm install globule@0.1.0-s npm install babel-generator@6.19.0-s npm Install Babel-helper-define-map@6.18.0-s We have 3 packages installed here that depend on Lodash, but Globule relies on

When you had a dependency that had dependencies on global variables (like jQuery or Lodash) or assumes that's this Boun D window to, you can use the Imports-loaderto provide those dependencies explicitly.In case there are one dependency that we use the need lodash, but didn ' t includes Lodash as dependency.One-to-solve the problem is so we can include

In the JavaScript language world, functions are first class citizens. JavaScript functions are objects that inherit from function, and functions can be used as arguments or return values for another function, which forms the high-order function (or function object) we often call. This constitutes the first element of functional programming. There are a number of functional programming libraries in the JavaScript world that can assist our JavaScript functional experience, the most successful of w

not apply.The first sin of Applet development: the NPM package cannot be called Although the require function is used to load dependencies when the mini-program development tool is packaged, it is not a complete CommonJS dependency management. Because the require function can only load JS files in the project, and the JS file path must be strictly defined. the path does not support the path style of CommonJS. For example, errors will occur in the following loading methods: require('

Make sure the installation is complete correctly, and see if there is a loadsh folder in the Node_modules directory> npm install lodash> ls node_modules for Windows #= Lodash# # # that version of the package was instal
