Here are the 6 common flaws to look out for in peer review: 1) Inappropriate study design for the study aims 2) Unexplained deviations from standard/best practice and methodologies 3) Over-interpretation of results In a manner more constructive than a LanguagePissingMatch, we ponder how the language could be made better at reasonable conceptual or implementation cost, and hopefully glean applicable insights along the way.. What goes in this List? XSS flaws can be difficult to identify and remove from a web application. Use Clojure or ClojureScript. Get rid of it, ECMA, please! The most common method of securing sensitive information that must be passed back and forth to a client is to: First, use SSL to encrypt the information over the 'wire'. Technical Article The encapsulated object of primitive types. It allows defining functions with the same name, the function defined later will override the one defined previously, it's hard for method overloading. But why use any of these frameworks, only to inflict JavaScript on yourself? JavaScript has only one numerical type and that’s (double precision) floating point. A common method of attack is to inject Javascript into the page via a form submission. Programmers often have to write workarounds for various problems in the language and these workarounds are immensely complex and cumbersome to understand. Frameworks come and go, depending on current trends and whims. JavaScript Object Notation (JSON) is a lightweight, text-based, language-independent data interchange format. JavaScript is now disabled in your Firefox browser. => Web =>  JavaScript. Having both is damn confusing. Summary JavaScript has a rich and fascinating history. And finally, JSLint’s output results are subject to interpretation and you need to decide what to do about them; sometimes, you actually want to break the “rules!” This additional cognitive burden only makes your job harder, as if programming wasn’t already hard enough. That new language is not JavaScript and is beyond the scope of this document. JavaScript’s C-like syntax robs it of Lisp’s clean and elegant syntax. Select the toggle to the right of javascript.enabled to change its value to false. Open Source Flaws Take Years to Find But Just a Month to Fix. Sometimes it may cause some errors difficult to find. It’s called jQuery and it’s all you really need to create a terrific UX. 2) JavaScript’s loose typing and aggressive coercions exhibit odd behaviour. Forget Angular, React, Backbone, Ember, Meteor, Polymer, Mithril, Aurelia, etc., etc. Researchers found that JavaScript, Ruby, PHP, and Java get most of their attack surface from transitive inclusions and .NET, Swift, and Go have more direct dependencies. Now, JavaScript has a Promise problem. Incidentally, ECMA should remove “==” and force everyone to use “===”. JavaScript doesn't have namespace, it's hard to be modular, there is no standard for putting codes in multiple source files. Lisp’s central data structure is the list .

JavaScript's global variables are visible in all modules, we can create global variable inside any function. If not for them, why would you use JavaScript??? NaN is a number, it means it overflows, it has some strange features: 8. For example, the module pattern and other attempts to create private scopes with localized state and logic that use closures and functions wrapped in functions, wrapped in functions, are beyond mad. I can defend the position. Implied global variables are especially problematic (“use strict” to avoid). Anything put in javaScript that is downloadable can be easily seen on the users device. null is not an object, as typeof incorrectly suggests. Every statement in JavaScript should be ended with semi-colon. JavaScript has three primitive data types: string, number and boolean. Further, there are multiple ways to handle object inheritance, making it difficult to decide which way to go. If a language possesses insane semantics, then it is dangerous to use. This is the only language I’ve ever used that doesn’t have an integer type (and I’ve used many). Lambdas do not make JavaScript Lisp-like, any more than C++, Java, Python, Haskell, and Smalltalk are Lisp-like. If one operand is string, the other operand is number, then the number will be converted to string automatically. The reserved word policies are much too strict. New Series!

Most of the time, you can get away with it, but there will come a day when it will bite you in the ass. Injection flaws allow attackers to relay malicious code through anapplication to another system. Write to me in PM. 0 == 0; // => true 0 == 1; // => false 0 == "0"; // … 10) The main draw of JavaScript is actually in frameworks like Node.js and AngularJS. null is one kind of object, it means the object is null; undefined is a data type, it means something undefined. This page describes design flaws in Java. Adobe fixed three critical-severity flaws in Adobe Prelude, Adobe Experience Manager and Adobe Lightroom. JavaScript is a dynamically typed, prototype-based programming language that honors the ECMAScript Standard, thus supporting imperative, object-oriented and functional programming paradigms. This makes it dicey to invest a great deal of time and effort in any one particular framework. But... [] + [] → "" // Empty string? 8) Asynchronous programming in JavaScript is very messy.

Promises were a big step forward for JavaScript, but unfortunately they have several design flaws. (shocking that it happens ;-) Here are some examples: Moreover, the designer didn't want to design it initially, he just wanted to complete the task assigned by company. There are many “gotchas” that can trip you up. Here’s the example document from the previous chapter:This page has the following structure:The data structure the browser uses to represent the document follows this shape. The JavaScript problem is two-fold and can be described thus: 1. Ambivalent The best way to find flaws is to perform a security review of the code and search for all places where input from an HTTP request could possibly make its way into the HTML output. (The transition from Angular 1.x to 2.0 has been especially disruptive.). JavaScript’s C-like syntax robs it of Lisp’s clean and elegant syntax. Data Types. I’m not a huge fan of languages without a strict type system, but I do recognize both their uses and their strengths for certain applications — if they didn’t screw this one up. JavaScript, the language.JavaScript, the language, has some issues that make working with it inconvenient and make developing software harder : 1. lack of module system (only pre-ES6), 2. weak-typing, 3. verbose function syntax1(pre-ES6), 4. late binding2, which has led to the creation of various static analysis tools to alleviate this language flaw3, but with limited success4 (there is even a static type checker5), 5. finicky equality/automatic conv… Use Amber. The authors have abused the language every which way, and we pay for it in terms of performance and/or ability to reason about the code. 3) Automatic semicolon insertion. This document describes ECMAScript Edition 3 (aka JavaScript 1.5). It is now a very powerful client side programming language used in almost all the websites. Below, I glean some of the best from various online sources…. It’s supported by every transpiled language. Microsoft and Netscape are developing a static revision which does not correct the language's flaws. This is a language issue because JavaScript’s nature makes it easy, and often necessary, to write convoluted, difficult-to-understand code. JavaScript's equality operator ( ==) breaks the equivalence relation of mathematics in that it performs type coercion when evaluating equality. It's very easy to mess up these two, but the meaning is completely different. This increases the complexity of program. This is nonsense. Performance Test for 5 JavaScript Object Iterations, Using JavaScript Objects Built into Browsers, Merge Two Sorted Arrays Without Extra Space Efficiently[O(1)] [Gap Method][Detailed & Simplified], JavaScript Best Practices — Event Listeners, Arrays, and null, GraphQL best practices: Use graphql-middleware for cross-cutting concerns, Understanding the nature of JavaScript deeply.

It’s super weird and unnecessary. The machine's ability to perceive the truth is dependent on the training set it had been given to produce the same. JavaScript and EcmaScript have their share of design flaws. This design increases the complexity of calculation. 7) Object prototypes do not scale well to large applications; it’s a rather primitive and sloppy way to do object-oriented programming (but it’s flexible!). JavaScript has its share of design errors, such as the overloading of + to mean both addition and concatenation with type coercion, and the error-prone with statement should be avoided.
