Operators for handling RxJS Observable of string
This library contains the RxJS Primitives for working with numbers including equality checks, formatting and creation.
Some methods from this library are based on ECMAScript String methods.

concat operator now supports passing of Observable value as parameterNew Operators (now String feature complete)
fromUnicode - Creates a string of Unicode Normalization Form characters
and uses String.prototype.normalize
to convert it to a stringmatch and matchAll for matching strings or regular expressions.match returns a single Array-like RegExpMatchArraymatchAll returns an array of Array-like RegExpMatchArrayrepeat - This repeats a string by the passed count number. This implementation accepts an optional separator character that can be used to generate strings such as CSVsearch - Searches a string and return the index of the resultpadStart and padEnd alias methods now added for paddingtrimLeft trimRight and trim alias methods now added for trimminges2018 to es2020PadPosition and TrimPosition enumsmapCodePointfromString now accepts both a single string value or array of string values. When passing an array
it acts the same as the from operator and also accept a scheduler.concat operator now accepts an argument list of strings or an array of stringsfromCharCode now accepts both a single string value or array of string values, but will only return a single string valuefromCodePoint now accepts both a single string value or array of string values, but will only return a single string valuemapCharCode now accepts an Observable single number or array of numbersmapCodePoint now accepts an Observable single number or array of numbersfrom* are being changed to filter* or map* as using from has a specific context in RxJS with creating Observable values.The following operators are affected:
fromCharCode to mapCharCode. For the new fromCharCode method, see the Added section below.fromCodePoint to mapCodePoint. For the new fromCodePoint method, see the Added section below.fromEndsWith to filterEndsWithfromIncludes to filterIncludesfromStartsWith to filterStartsWithfromString - Creates an Observable string from the string passed as it's parameterfromCharCode method now takes an array of numbers that are char codes and returns an Observable string valuefromCodePoint method now takes an array of numbers that are char codes and returns an Observable string valuetitleize - Operator for taking a string and capitalising first character of each word (title case)reverse - Operator for reversing a stringcodePointAt - Returns the code point at a specified index position of an Observable<string>concat - Returns a string of the original Observable<string> concatenated with additional string passed as parametersfromCharCode - Generates a string based on an array of character codesfilterCodePoint - Generates a string based on an array of code pointsfromStartsWith - Returns the String value of a Observable<string> that starts with a specified characterlastIndexOf - Returns a Number last index of a specified string in a Observable<string> valueslice- Returns a substring String of the original Observable<string> from start index to optional end indexsplit - Returns a string[] of strings spit from the original Observable<string> using a separator propertystartsWith - Returns a Boolan value if an Observable<string> starts with a specified characterInitial release of library
charAt - Returns the character at a specified index position of an Observable<string>charCodeAt - Returns the character code at a specified index position of an Observable<string>endWith - Returns a Boolan value if an Observable<string> ends with a specified characterfromEndsWith - Returns the String value of a Observable<string> that ends with a specified characterfromIncludes - Returns the String value of a Observable<string> that includes a specified stringincludes - Returns the Boolean value of a Observable<string> that includes a specified stringindexOf - Returns a Number index of a specified string in a Observable<string> valuepadString - Returns a padded string, padded from 'start' or 'end' to a specified length and optional pad characterreplace - Returns a String where the original Observable<string> is modified with a regex or string search string, and replacement character or stringsubstring - Returns a substring String of the original Observable<string> to the specified start position and lengthtoLowerCase - Returns a localised lower-case String of the original Observable<string> valuetoUpperCase - Returns a localised upper-case String of the original Observable<string> valuetrimString - Returns a String value that has white space trimmed from the original Observable<string> - can be 'start', 'end' or 'all'
