Values, Types, and Operators :: Eloquent JavaScript - 0 views

eloquentjavascript.net/01_values.html

javascript programming

shared by fspore on 27 Jun 15 - No Cached
  • Not all operators are symbols. Some are written as words. One example is the typeof operator, which produces a string value naming the type of the value you give it.
  • Having such numbers is useful for storing strings inside a computer because it makes it possible to represent them as a sequence of numbers. When comparing strings, JavaScript goes over them from left to right, comparing the numeric codes of the characters one by one.
  • There is only one value in JavaScript that is not equal to itself, and that is NaN, which stands for “not a number”.
  • ...16 more annotations...
  • In practice, you can usually get by with knowing that of the operators we have seen so far, || has the lowest precedence, then comes &&, then the comparison operators (>, ==, and so on), and then the rest. This order has been chosen such that, in typical expressions like the following one, as few parentheses as possible are necessary:
  • The difference in meaning between undefined and null is an accident of JavaScript’s design, and it doesn’t matter most of the time. In the cases where you actually have to concern yourself with these values, I recommend treating them as interchangeable (more on that in a moment).
  • . Yet in the third expression, + tries string concatenation before numeric addition
  • When something that doesn’t map to a number in an obvious way (such as "five" or undefined) is converted to a number, the value NaN is produced.
  • Further arithmetic operations on NaN keep producing NaN, so if you find yourself getting one of those in an unexpected place, look for accidental type conversions.
  • g ==, the outcome is easy to predict: you should get true when both values are the same, except in the case of NaN.
  • But when the types differ, JavaScript uses a complicated and confusing set of rules to determine what to do. In most cases, it just tries to convert one of the values to the other value’s type. However, when null or undefined occurs on either side of the operator, it produces true only if both sides are one of null or undefined.
  • That last piece of behavior is often useful. When you want to test whether a value has a real value instead of null or undefined, you can simply compare it to null with the == (or !=) operator.
  • The rules for converting strings and numbers to Boolean values state that 0, NaN, and the empty string ("") count as false, while all the other values count as true.
  • where you do not want any automatic type conversions to happen, there are two extra operators: === and !==. The first tests whether a value is precisely equal to the other, and the second tests whether it is not precisely equal. So "" === false is false as expected.
  • The logical operators && and || handle values of different types in a peculiar way. They will convert the value on their left side to Boolean type in order to decide what to do, but depending on the operator and the result of that conversion, they return either the original left-hand value or the right-hand value.
  • The || operator, for example, will return the value to its left when that can be converted to true and will return the value on its right otherwise. This conversion works as you’d expect for Boolean values and should do something analogous for values of other types.
  • This functionality allows the || operator to be used as a way to fall back on a default value. If you give it an expression that might produce an empty value on the left, the value on the right will be used as a replacement in that case.
  • The && operator works similarly, but the other way around. When the value to its left is something that converts to false, it returns that value, and otherwise it returns the value on its right.
  • Another important property of these two operators is that the expression to their right is evaluated only when necessary. In the case of true || X, no matter what X is—even if it’s an expression that does something terrible—the result will be true, and X is never evaluated. The same goes for false && X, which is false and will ignore X. This is called short-circuit evaluation.

  • I used to be a contractor for Apple, working on a secret project. Unfortunately, the computer we were building never saw the light of day. The project was so plagued by politics and ego that when the engineers requested technical oversight, our manager hired a psychologist instead. In August 1993, the project was canceled. A year of my work evaporated, my contract ended, and I was unemployed.

      This is why free/open source software is a good idea. If a company kills a project it could still be a benefit to the rest of the software world.

  • Everyone will benefit, even the Java community: Now that there's competition again, new constructs are—surprise!—again being considered for Java
  • Do languages have to sacrifice anything?
  • .NET goes much further: A routine written in a language L1 may call another routine written in a different language L2. A module in L1 may declare a variable whose type is a class declared in L2, and then call the corresponding L2 routines on that variable. If both languages are object oriented, a class in L1 can inherit from a class in L2. Exceptions triggered by a routine written in L1 and not handled on the L1 side will be passed to the caller, which—if written in L2—will process it using L2's own exception-handling mechanism. During a debugging session, you may move freely and seamlessly across modules written in L1 and L2. I don't know about you, but I've never seen anything coming even close to this level of interoperability.

      So, can anyone build a Sun storage device, or are Sun's "general purpose server parts" better (with better management and redundancy ...) ?
  • using a general purpose OS allows us to easily embrace specialized components (from flash memory to GPU's)

      Schwartz gives the strong impression of an IT company _without_ its hand in your pocket. It is a similar attitude and reputation, though with proprietary software, rather than services (for free software), that seems to have made Microsoft so wealthy in the late eighties and nineties.
  • Solaris OEM agreements with IBM, Dell, Intel, Fujitsu and HP are so important to our end customers - they know they'll never be locked in.
  • These open source platforms generate, alongside the services attached to them, over a billion dollars a year, making Sun by far and away the world's largest open source software company.

      This constructors lies, wondeful!
  • Again, we augment Function. We make an instance of the parent class and use it as the new prototype. We also correct the constructor field, and we add the uber method to the prototype as well.
  • This adds a public method to the Function.prototype, so all functions get it by Class Augmentation. It takes a name and a function, and adds them to a function's prototype object.
  • ...3 more annotations...
  • To make the examples above work, I wrote four sugar methods. First, the method method, which adds an instance method to a class. Function.prototype.method = function (name, func) { this.prototype[name] = func; return this; };
  • JavaScript can be used like a classical language, but it also has a level of expressiveness which is quite unique. We have looked at Classical Inheritance, Swiss Inheritance, Parasitic Inheritance, Class Augmentation, and Object Augmentation. This large set of code reuse patterns comes from a language which is considered smaller and simpler than Java.
  • I have been writing JavaScript for 8 years now, and I have never once found need to use an uber function. The super idea is fairly important in the classical pattern, but it appears to be unnecessary in the prototypal and functional patterns. I now see my early attempts to support the classical model in JavaScript as a mistake.

Q&A BPMN versus UML modeling

shared by Fabien Cadet on 18 Jul 11 - No Cached
  • On the other hand, BPMN has been designed with the aim of being a notation for high-level modeling.
  • BPMN models are not intended to be directly executed. They need to be refined (e.g. into BPEL processes) prior to execution.
  • At the most, BPMN might be used to generate "templates of BPEL code" that developers will have to refine to obtain a running implementation.
  • ...1 more annotation...
  • In fact, one could safely bet that a lot of people will define BPMN models for the pure purpose of documenting business processes, and not for the purpose of developing software. Many BPMN models will never be executed or lead to any piece of software. They'll just be used as part of a methodology for business improvement.
