About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
isAnagram
Test if a value is an anagram.
Installation
npm install @stdlib/assert-is-anagramAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (see README). - To use as a general utility for the command line, install the corresponding CLI package globally.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
Usage
var isAnagram = require( '@stdlib/assert-is-anagram' );isAnagram( str, value )
Tests if a value is an anagram.
var str = 'I am a weakish speller';
var value = 'William Shakespeare';
var bool = isAnagram( str, value );
// returns trueNotes
- The function does not address the presence of diacritics.
- Only alphanumeric characters are considered.
- Capitalization is ignored.
- If provided a non-string for the first
argument, the function throws anError. - If provided a non-string for the second
argument, the function returnsfalse.
Examples
var isAnagram = require( '@stdlib/assert-is-anagram' );
var bool = isAnagram( 'I am a weakish speller', 'William Shakespeare' );
// returns true
bool = isAnagram( 'bat', 'tab' );
// returns true
bool = isAnagram( 'bat', 'TAB' );
// returns true
bool = isAnagram( 'bat', 't a b' );
// returns true
bool = isAnagram( 'bat 321', 'tab 123' );
// returns true
bool = isAnagram( 'bat', 'tabba' );
// returns false
bool = isAnagram( 'bat', 5 );
// returns false
bool = isAnagram( '123', 321 );
// returns falseCLI
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/assert-is-anagram-cliUsage
Usage: is-anagram [options] [<string>] --str=<string>
Options:
-h, --help Print this message.
-V, --version Print the package version.
--str string Comparison string.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
Notes
-
If the split separator is a regular expression, ensure that the
splitoption is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'baz\ntab' | is-anagram --str=zab --split /\r?\n/ # Escaped... $ echo -n $'baz\ntab' | is-anagram --str=zab --split /\\r?\\n/
-
The implementation ignores trailing delimiters.
Examples
$ is-anagram baz --str=zab
trueTo use as a standard stream,
$ echo -n 'tab\nbaz' | is-anagram --str=bat
true
falseBy default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
$ echo -n 'tab\tbaz' | is-anagram --str=bat --split '\t'
true
falseSee Also
