Regular expressions are patterns used to match character combinations in strings.
In JavaScript, regular expressions are also objects.

Constructor Summary

Constructors
Constructor	Description
`RegExp(String pattern)`	Creates a regular expression. See MDN RegExp.
`RegExp(String pattern, String flags)`	Creates a regular expression, using flags passed as string. If specified, flags is a string that contains the flags to add. Alternatively, if an object is supplied for the pattern, the flags string will replace any of that object's flags (and lastIndex will be reset to 0). Flags may contain any combination of the following characters: g (global match), finds all matches rather than stopping after the first match.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`RegExpResult`	`exec(String s)`	Executes a search for a match in a string. It returns an array of information or null on a mismatch.
`static int`	`getLastIndex()`	Returns the index at which to start the next match. This property is set only if the regular expression instance used the g flag to indicate a global search, or the y flag to indicate a sticky search. The following rules apply: If lastIndex is greater than the length of the string, `test(String)` and `exec(String)` fail, then lastIndex is set to 0 If lastIndex is equal to or less than the length of the string and if the regular expression matches the empty string, then the regular expression matches input starting from lastIndex.
`String`	`getSource()`	Returns a string containing the source text of the `RegExp` object, and it doesn't contain the two forward slashes on both sides and any flags.
`boolean`	`isDotAll()`	Returns `true` whether or not the "s" flag is used with the regular expression. It is a read-only property of an individual regular expression instance.
`boolean`	`isGlobal()`	Returns `true` whether or not the "g" flag is used with the regular expression. It is a read-only property of an individual regular expression instance.
`boolean`	`isIgnoreCase()`	Returns `true` if the "i" flag was used; otherwise, `false`. The "i" flag indicates that case should be ignored while attempting a match in a string. It is a read-only property of an individual regular expression instance.
`boolean`	`isMultiline()`	Returns `true` whether or not the "m" flag is used with the regular expression. It is a read-only property of an individual regular expression instance.
`boolean`	`isSticky()`	Returns `true` whether or not the search is sticky (searches in strings only from the index indicated by the last index property of this regular expression). It is a read-only property of an individual regular expression instance.
`boolean`	`isUnicode()`	Returns `true` whether or not the "u" flag is used with a regular expression. It is a read-only property of an individual regular expression instance.
`boolean`	`test(String value)`	Executes a search for a match between a regular expression and a specified string.

- Constructor Detail
  - RegExp
```
public RegExp(String pattern)
```
    Creates a regular expression.
    See MDN RegExp.
    
    Parameters:
    
    pattern - the text of the regular expression.
    Patterns can include special characters so they can match a wider range of values than would a literal string.
  - RegExp
```
public RegExp(String pattern,
              String flags)
```
    Creates a regular expression, using flags passed as string.
    If specified, flags is a string that contains the flags to add.
    Alternatively, if an object is supplied for the pattern, the flags string will replace any of that object's flags (and lastIndex will be reset to 0).
    Flags may contain any combination of the following characters:
    
    g (global match), finds all matches rather than stopping after the first match.
    i (ignore case), if u flag is also enabled, uses Unicode case folding.
    m (multiline) treats beginning and end characters (^ and $) as working over multiple lines.
    In other words, match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string.
    s ("dotAll") allows . to match newlines.
    u (unicode) treats pattern as a sequence of Unicode code points.
    y (sticky) matches only from the index indicated by the lastIndex property of this regular expression in the target string.
    Does not attempt to match from any later indexes.
    
    See MDN RegExp.
    Parameters:
    
    pattern - the text of the regular expression.
    Patterns can include special characters so they can match a wider range of values than would a literal string.
    
    flags - If specified, flags is a string that contains the flags to add.
    Alternatively, if an object is supplied for the pattern, the flags string will replace any of that object's flags (and lastIndex will be reset to 0).
    Flags may contain any combination of the following characters:
    
    g (global match), finds all matches rather than stopping after the first match.
    i (ignore case), if u flag is also enabled, uses Unicode case folding.
    m (multiline) treats beginning and end characters (^ and $) as working over multiple lines.
    In other words, match the beginning or end of each line (delimited by \n or \r), not only the very beginning or end of the whole input string.
    s ("dotAll") allows . to match newlines.
    u (unicode) treats pattern as a sequence of Unicode code points.
    y (sticky) matches only from the index indicated by the lastIndex property of this regular expression in the target string.
    Does not attempt to match from any later indexes.
- Method Detail
  - getLastIndex
```
@JsProperty
public static int getLastIndex()
```
    Returns the index at which to start the next match.
    This property is set only if the regular expression instance used the g flag to indicate a global search, or the y flag to indicate a sticky search.
    The following rules apply:
    
    If lastIndex is greater than the length of the string, test(String) and exec(String) fail, then lastIndex is set to 0
    If lastIndex is equal to or less than the length of the string and if the regular expression matches the empty string, then the regular expression matches input starting from lastIndex.
    If lastIndex is equal to the length of the string and if the regular expression does not match the empty string, then the regular expression mismatches input, and lastIndex is reset to 0.
    Otherwise, lastIndex is set to the next position following the most recent match.
    Returns:
    
    the index at which to start the next match
  - isDotAll

@JsProperty
public boolean isDotAll()
