因此,虽然 JavaScript 执行时像是在编译或者像是一种编译和解释的混合,我仍然认为 JavaScript 是一个解释型语言或者是一个今天很多人说的混合型语言,而不是编译型语言。 关于本文 译者:@Anx 译文:https://segmentfault.com/a/1190000013126460 作者:@Paul Shan 原文:http://voidcanvas.com/is-javascript-really-i...
几天前一个刚接触 JavaScript 的朋友问我 JavaScript 是编译型语言还是解释型语言。从一个初学者那里听到这样的问题让我有些惊讶,因为所有初学者都知道 JS 是一个解释型语言;特别是像她这样之前使用过 Java 这类语言的初学者。 当一些人深入 JavaScript 并且开始研究 V8 引擎、SpiderMonkey、JIT 之类东西的时候,他们...
JavaScript is an object-based scripting language. Syntax: JavaScript syntax is not as formal or structured as Java. Thus, it’s simpler for most users. Compilation: Java is a compiled language, whereas JavaScript is an interpreted language that is interpreted line by line at run-time; compiled...
JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. 现在我们应该对这个定义中的后面一段话有着更深入的理解——“JavaScript (JS) 是解释型或即时编译型的编程语言”。 从对JavaScript 编译的疑问开始,我们就像拿到了一块拼图...
What is JavaScript engine? - 什么是 JavaScript 引擎? As you may heard before, JavaScript is an interpreted programming language. It means that source code isn’t compiled into binary code prior to execution. 你一定有所耳闻,JavaScript 是一门解释执行语言。这意味着源代码在执行前,无需编译为二进制...
JavaScript is an interpreted, object-based scripting language. Although it has fewer capabilities than full-fledged object-oriented languages like C++, JavaScript is more than sufficiently powerful for its intended purposes.JavaScript is not a cut-down version of another language (it is only distantly...
JavaScript is a sophisticated, general-purpose, object-oriented, interpreted programming language originally developed by Netscape Communications Corporation for building Web applications that require client-side processing (i.e., processing that occurs in the browser). In addition, JavaScript is a non-...
JavaScript (JS) is a dynamic interpreted language that powers the web. It is widely used in browsers (where JS scripts are interpreted by JavaScript engines like Chrome's V8) and increasingly on servers (on a Node.js runtime environment). JS is a prototype-based scripting language with first...
JavaScript syntax is based on the popular programming languages C, C++, and Java, which makes it familiar and easy to learn for experienced programmers. At the same time, JavaScript is an interpreted scripting language, providing a flexible, forgiving programming environment in which new programmers...
