传输数据的程序: sap中两个不相关的程序之间数据传输 普遍用的是memory,就是把数据上传到内存,然后在从内存中取出 下面简单写一些memory的写法 传输数据的程序: 接受数据的程序: 大概就是这种形式吧。 可以传递单值,或者一个内表,或者多个值。
As LokiJS is written in JavaScript it can be run on any environment supporting JavaScript such as browsers, node.js/node-webkit, nativescript mobile framework and hybrid mobile apps (such as phonegap/cordova).Made by @techfort, with the precious help of Dave Easterday....
Making source-maps to work, so that the error points to the Typescript code and not the compiled in memory Javascript. Support for typescript extensions Introducing some sort of caching to avoid re-compiling the unchanged files. Typescript compiler is not one of the fastest compilers, so cachi...
JavaScript—window.close(); When using this technique, make sure you don’t ship your product with this code in place. Your app won’t invoke any code that triggers on suspension and will need to be reactivated (instead of resumed) each time it’s opened. This technique...

Java heap leaks: the classic memory leak in Java, in which objects are continuously created without being released. This is usually caused by latent object references. Native memory leaks: associated with any continuously growing memory utilization that is outside the Java heap, such as allocations...
JavaScript, the powerhouse behind many applications, sometimes faces limitations when it comes to memory in a Node.js environment. Today, let's dive into a common challenge faced by many applications - the default memory limit in Node.js. In this blog post, we'll exp...
So far you’ve been exposed to the web workers API for browsers, covered in Chapter 2, and the worker threads module for Node.js, covered in “The worker_threads Module”. These are two powerful tools for working with concurrency in JavaScript, allowing developers to run code in parallel ...
But, in Javascript, memory is freed lazily, with a garbage collection. This means that, when an object is not used anymore, its memory is not immediately disposed. Garbage collector will explore which objects are disposable later, and free them when it is convenient. ...
