Seven Notes for beginners of JavaScript
Each language has a special place. For JavaScript, using var can declare any type of variables. This script language looks very simple, however, to write elegant code, you need to constantly accumulate experience. This article lists seven details that JavaScript Beginners should pay attention.
(1) simplified code
It is very simple to define objects and arrays in JavaScript. We want to create an object, which is generally written as follows:Var car = new Ob
:
var moviesthatneedbetterwriters = new Array (
' Transformers ', ' Transformers2 ', ' Avatar ', ' Indiana Jones 4 '
);
Use abbreviated statements:

var moviesthatneedbetterwriters = [
' Transformers ', ' Transformers2 ', ' Avatar ', ' Indiana Jones 4 '
];
Another question about arrays is whether there is an associative array of suc

The GPU represents a graphics processing unit, but there are other uses for these tiny chips in addition to working with graphics. For example, Google uses the GPU to model the human brain, and Salesforce relies on the GPU to analyze Twitter-based microblogging data streams. The GPU is well suited for parallel processing operations, which means performing thousands of tasks at the same time. How do you do it? You have to develop a new software that allows it to tap the potential of a GPU chip. E
not only a "flexible", but also from the functional language inside the "learning" come over. At the earliest, C + + programmers didn't really know what to functor. If you take a test, you will find that C + + was born in 1983, and Scheme was born in 1975, and Lisp was born in 1958. The birth of C + + was 8 years later than scheme, but scheme began with lexical scoping lambda. Functor is nothing more than a curved imitation of lambda. In fact, some of the things that C + + added later (includin
