Variable namingIf the variables of the intrinsic function and the variable name of the external function are the same, then the intrinsic function cannot point to the variable with the same name as the outer function.Like what:function foo (num) { returnfunction(num) { console.log (num); }} var New foo (9// undefinedIn fact, the above usage, the jargon called function currying, is to transform a function that accep

Binary adder1) If you want to build a computer, then the first thing you can calculate the sum of two number of devices (in fact, the original addition calculation is the only work the computer to do).2) adder = wire + switch + bulb + battery + relay (fully used in binary calculation)3) Addition and carry in the adder is separate, the result of the addition of the two binary numbers is by the XOR gate (
declaration is nested within another function. As with the nesting of blocks, the inner variables can obscure the outer variables of the same name, and the outer variables can be used directly in the inner layer. If the base parameter of add is the outer layer of the closure returned by return, its value 5 is still present after the add is returned and assigned to ADD5. When ADD5 executes, parameter I can be added from the base of the outer layer, resulting in a result of 15.

FiguresTo insert a figure in a LaTeX document, you write lines like this:\begin{figure} \centering \includegraphics[width=3.0in]{imagefile1} \caption{caption for figure} \label{fig:sample_figure}\end{figure}The whole block is enclosed between \begin{figure} and \end{figure} . The command \includegraphics does the actual insertion of the image. The file name of the inserted image is imagefile1 .

completed, some manipulation of the obtained data is performed, and the operation can be given to the function object for processing.In addition, in some common operations, there are often different special operations, while the differential operation can be encapsulated with a function.

as an argument and then returns an alternate version of the function.
Let's look at a simple example:
def add_number (func):d EF Adder (ARG): return func (ARG) +100return adderdef f (x): Return Xf=add_number (f) Print F (20)
Add_number is an adorner function that takes a function (f) as a parameter, and then returns another function (adder) to the original function, so that the original function does not

In earlier C # versions, if you cannot use cyclic variables in Lambda syntax in cyclic statements. Actually, worse than you think, when you use loop variables in Lambda syntax, it will give you the wrong result-it is the initial value of the loop rather than the final value.
For example, the following is a method that returns a series of 'adder' values. Each 'adder
1, variables (such as defining a four-byte variable int var) in the memory of the format is big-endian or small-end? For example, define a variable int var = 1; If the CPU is a 32-bit CPU, the compiler will assign a value of 4 bytes in memory to 0x01,0x00,0x00,0x00, then the CPU reads in memory according to the address of the variable. This successive 4 bytes into its own register, and then the adder of the CPU adds the 4 bytes of content (as a value
The function is also a value.

Call the method on the Controller
After a controller is created on an HTML element, you can call the preceding method. The first parameter is the method name, followed by the required parameters of the method, as shown in the following example:
