Reference typeIn ECMAScript, a reference type is a data structure that organizes data and functionality together, and reference types are sometimes referred to as object definitions because they describe the properties and methods that a class of objects have. (Note: Although ECMAScript is technically an object-oriented language, it does not have the basic architecture of classes and interfaces supported by traditional object-oriented languages.) )1.O

3. Pre-increment/pre-increment operators: two operators borrowed from C. Example:
The Code is as follows:
Var iNum = 10;Console. log (++ iNum); // outpus 11 same as iNum = iNum + 1Console. log (iNum); // outpus 11Console. log (-- iNum); // outpus 10 same as iNum = iNum-1Console. log (iNum); // outpus 10

Question 1:
The number 1-10 ^ n contains the number 3. N
Problem solving process:
1. This question is accurate + recursive .. If n = 1000, assume that the single digit is 3 and the other 999 digits are arbitrary .. Then there will be 10 ^ 999 numbers.
2. Use F [I] to indicate the number of all BITs that contain I. g [I] indicates the number of 3 contained in

can see the processing results of three different function forms. In PB11.2, regular functions (such as left and len) can fully process dual characters.W"It is absolutely necessary to be deprecated. However, single-byte functions (with"A") Is still processed by single byte, and is more effective than PB8.02 in identifying single-byte and double-byte strings.
In addition, the Unicode support for PB11.2 can be seen through an example, the call to an API written in VC ++, the API function protot

There are two types of ECMAScript integers, that is, signed integers (allowed with positive and negative numbers) and unsigned integers (only positive numbers are allowed). In ECMAScript, all integer literals by default are signed integers, what does that mean?
A signed integer uses a 31-bit numeric value that represents an integer, a symbol with a 32nd digit integer, 0 for a positive number, and a 1 for negative numbers. Values range from 2147483648
