In daily project development, we often need to package for testing, especially in windows, while in Linux.
In this case, many programmers need to pack a package and pack a package later. These packages may be large. In fact, only the code is changed, while the jar package is basically unchanged.
Of course, many people may say automated testing. Well, what we need to do today is the first step of automated testing.
At this time, I can use ant to packag
Ant is a Java-based build tool. Theoretically, it is somewhat similar to make in (Unix) C, but without the bug of make.Now that we've got make, Gnumake, NMAKE, jam, and other build tools, why do we need a new build tool? The limitations and inconveniences of these tools cannot be tolerated because Ant's original authors develop software on multiple (hardware) platforms. Tools like make are inherently shell-based: They compute dependencies and then exe

Most of the time, the main cause of confusion on the scope is that it is unclear whether to search for variables based on the nested order of the function location or the call sequence of the function. Coupled with the interference of this mechanism, variable search is prone to e

Understanding of javascript scopes and scopesThe JavaScript scope is the accessible range of variables and functions. 1. The variable scope is in JavaScript, and the variable scope is divided into global scope and local scope. Variables with global scopes can be defined anywhere. variables declared without var (excluding function parameters) have a global scope and become global variables. Therefore, you mu
JavaScript One, no block-level scope in JavaScript
A brace is scoped to a block-level scope, and block-level scopes exist in Java and C #
function Main () { if (1==1) { var name = ' seven '; } Console.log (name);} Output: SevenSecond, JavaScript uses function scope
In JavaScript each function acts as a scope, outside of which the variables in the internal scope cannot be accessed
function Main () { var in
(typeof S); // string 8 alert (typeof B); // Boolean 9 alert (typeof I); // Number 10 alert (typeof U ); // undefined 11 alert (typeof N); // object 12 alert (typeof O); // objectCopy the Code. However, in terms of detecting the referenced data type, typeof is not powerful. You need to use the instanceof OPERATOR:
1 alert (person instanceof object); // is the person object type?

Understanding of JavaScript scopes and block-level scopes, and understanding of javascript concepts
Scope is always the top priority of any programming language, because it controls the visibility and lifecycle of variables and parameters. Here, we first understand two concepts: block-level scope and function scope.
What is block-level scope?
The statement set in any pair of curly braces ({And}) belongs to
In Python, variable lookup follows the LGB principle of prioritizing a variable in a local scope (regional scope), failing to find it in the global scope, and finally trying to find it in the built-in scope (build-in scope). If it is still not found, an exception is thrown. Later, due to the appearance of closures and nested functions, the scope adds an external scope, so that the lookup scope priority of the variable becomes: local, external, global, and built-in.

JS variables and their scopes, JS variable scopes
1. variables and their scopes: variables are classified into "global variables" and "local variables". The "global variables" are declared outside the function and can be used by all functions, the "local variable" is declared within the function body and can only be used in the function that defines the variable.
var ClassA = function () {this. Prop1 = 1;} classa. Prototype. func1 = function () {var = this, var1 = 2; function A () {return function () {alert (VAR1); Alert (this. prop1); } . Apply (that); } ; A (); var obja = new ClassA (); Obja. Func1 ();
