C#, C++, JavaScript, Java String, StringBuilder class study

July 3, 2016

 Spend time to work on String class API on C#, C++, JavaScript, Java language. Always keep busy, study APIs first, go over all APIs.

1. C# programming language:

 First, work on C# StringBuilder class:
 https://msdn.microsoft.com/en-us/library/system.text.stringbuilder(v=vs.110).aspx

2. C++ string class study (30 minutes a time)
Review and go through each one (30 minutes study ......)


http://www.cplusplus.com/reference/string/string/

member type (12):
value_type      char
traits_type     char_traits<char>
allocator_type  allocator<char>
reference       char&
const_reference const char&
pointer         char*
iterator        a random access iterator to char (convertible to const_iterator)
const_iterator  a random access iterator to const char
reverse_iterator  reverse_iterator<iterator>
const_reverse_iterator reverse_iterator<const_iterator>
different_type  ptrdiff_t
size_type       size_t

questions: traits_type ?

Iterators (8):
begin
end
(C++ 11)
rbegin
rend
cbegin
cend
crbegin
crend

Capacity (9):
size
length
max_size
resize
capacity
reserve
clear
empty
shrink_to_fit  (C++ 11)


Element access (3)
operator[]
at
back    - access last character
front   - access first character


Modifiers (9):
operator+=
append
push_back
assign
insert
erase
replace
swap
pop_back


String operations (12):
c_str
data
get_allocation
copy
find
rfind
find_first_of
find_last_of
find_first_not_of
find_last_not_of
substr
compare

Member constants
npos - maximm value for size_t

Non-member function overloads (6)
operator+
relational operators
swap
operator>>
operator<<
getline


3. JavaScript String reference (30 minutes a time to study)
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String

Properties:
string.prototype
string.length

Methods:

Exclude deprecated methods, try to remember all the following methods: 34 methods

String.fromCharCode()
String.fromCodePoint()


String.prototype.anchor()
String.prototype.charAt()
String.prototype.codePointAt()
String.prototype.concat()
String.prototype.endsWith()


String.prototype.includes()
String.prototype.indexOf()
String.prototype.lastIndexOf()
String.prototype.link()
String.prototype.localeCompare()


String.prototype.match()
String.prototype.normalize()
String.prototype.repeat()
String.prototype.replace()
String.prototype.search()


String.prototype.slice()
String.prototype.split()
String.prototype.startsWith()
String.prototype.normalize()
String.prototype.substr()

String.prototype.substring()
String.prototype.toLocaleLowerCase()
String.prototype.toLocaleUpperCase()
String.prototype.toLowerCase()
String.prototype.toString()

String.prototype.toUpperCase()
String.prototype.trim()
String.prototype.trimLeft()
String.prototype.trimRight()
String.prototype.valueOf()


String.prototype[@@iterator]()
String.raw()

July 7, 2016 - Reading time: more than 30 minutes

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substring

substring
data descriptor/ accessor descriptor

In order to understand string - JavaScript, go through a lot of topics:

10 minutes reading of define property
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty

string literal
global object directly
Template literals

back-tick (` `)
Expresssion interpolation
syntactic sugar making substitutions like this more readable

tagged template literal - more advanced form of template literals

Another 10 - 15 minutes reading of template literals

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals
