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

  • 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.

  • The updateURL uses https, or there is no updateURL at all (which defaults to addons.mozilla.org which is https) The updateURL uses http and the updateKey entry is specified which will be used to verify the data in the update manifest.
  • In the update manifest delivered from the updateURL the updateLink must be specified in one of the following ways: The updateLink to the XPI file must use https The updateLink can use http and you must include an updateHash for the XPI file using sha1, sha256, sha384 or sha512 hash algorithms.

Writing Custom Code - Your Code, Our Cloud - 0 views

  • App42 platform has various technical and business services using which app development can be done without writing a single line of backend code. However there might be a case where the app developer might need to have some server side custom code for their app. There could be multiple scenarios for example- You want to add server side validation and or custom logic on the input data instead of on the client. You want to make a custom service by aggregating two or more App42 services. For example aggregating Push and Storage service for custom requirement. App logic that might get changed in future and hence you don’t want to bundle it in your app. Instead you would like to put it on the server where it can be accessed through REST calls from your app.

What Are Low Code And Less Code Development Platforms? - 0 views

  •  
    Enterprise and citizen developers can create mobile or web apps by dragging and dropping application components into low-code or no-code development platforms, connecting them, and adding code as needed. These platforms and the on-demand app development services they provide are frequently used interchangeably.

2000: Things You Should Never Do, Part I - Joel on Software - 10 views

    "There's a subtle reason that programmers always want to throw away the code and start over. The reason is that they think the old code is a mess. And here is the interesting observation: they are probably wrong. The reason that they think the old code is a mess is because of a cardinal, fundamental law of programming: It's harder to read code than to write it. "

Checking OpenCV with PVS-Studio - 0 views

  •  
    OpenCV is a library of computer vision algorithms, picture processing algorithms, and general-purpose numerical algorithms. The library is written in C/C++ and is free both for academic and commercial use, as it is distributed under the BSD license. The time has come to check this library with the PVS-Studio code analyzer. OpenCV is a large library. It contains more than 2500 optimized algorithms and consists of more than 1 million code lines. Cyclomatic complexity of the most complex function cv::cvtColor() is 415. It is no wonder that we have found quite many errors and questionable fragments in its code. However, the size of the source code taken into account, we may call this library a high quality one.

The Archive of Interesting Code - 0 views

  •  
    The Archive of Interesting Code is an (ambitious) effort on my part to research, intuit, and code up every interesting algorithm and data structure ever invented. In doing so, I hope both to learn the mathematical techniques that power these technologies and to improve my skills as a programmer. The examples on this site are in a variety of languages. I generally prefer to use C++ for algorithms, since the STL provides a great framework for expressing algorithms that work on a variety of data types. I code up most data structures in Java, both because the Collections framework allows them to be integrated in seamlessly with other applications and because automatic garbage collection simplifies some of the resource management. Every now and then I'll find an algorithm or data structure that is best represented in a different language like Haskell, in which case I'll forgo my usual language conventions.
