Determine columns needed for a fixed-size wide-character string
wcwidth is a simple JavaScript port of wcwidth implemented in C by Markus Kuhn.
JavaScript port originally written by Woong Jun woong.jun@gmail.com (http://code.woong.org/)
'í•ś'.length // => 1
wcwidth('í•ś'); // => 2
'한글'.length // => 2
wcwidth('한글'); // => 4
wcwidth() and its string version, wcswidth() are defined by IEEE Std
1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used
to represent the given wide character and string.
Markus's implementation assumes the wide character given to those functions to be encoded in ISO 10646, which is almost true for JavaScript's characters.

Similar to wcwidth, string-width calculates and returns the display width of a string in the terminal. It handles emojis and other wide characters as well. The main difference is in the implementation details and dependencies, where string-width might use a different approach or have updated character width mappings compared to wcwidth.
This package focuses on determining the East Asian Width property of characters, which is closely related to the functionality provided by wcwidth. While wcwidth calculates the display width considering various character properties, eastasianwidth specifically targets the classification of characters based on the East Asian Width attribute, which can be useful for applications dealing with East Asian languages.
