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!
Remove Words
Remove a list of words from a string.
Installation
npm install @stdlib/string-remove-wordsAlternatively,
- 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 removeWords = require( '@stdlib/string-remove-words' );removeWords( str, words[, ignoreCase] )
Removes all occurrences of the given words from a string.
var str = 'beep boop Foo bar';
var out = removeWords( str, [ 'boop', 'foo' ] );
// returns 'beep Foo bar'By default, words are removed from an input string in case of an exact match. To perform a case-insensitive replace operation, set ignoreCase to true.
var str = 'beep boop Foo bar';
var out = removeWords( str, [ 'boop', 'foo' ], true );
// returns 'beep bar'Examples
var removeWords = require( '@stdlib/string-remove-words' );
var stopwords = require( '@stdlib/datasets-stopwords-en' );
var inmap = require( '@stdlib/utils-inmap' );
var spam = require( '@stdlib/datasets-spam-assassin' );
var corpus = spam();
var words = stopwords();
function remove( mail, idx ) {
var newText = removeWords( mail.text, words );
console.log( 'After removing stop words, email %d contains %d characters. Originally, it contained %d.', idx, newText.length, mail.text.length );
mail.text = newText;
}
inmap( corpus, remove );CLI
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/string-remove-words-cliUsage
Usage: remove-words [options] [<string>] --words=<string>
Options:
-h, --help Print this message.
-V, --version Print the package version.
--words w1,w2,... Comma-separated list of words.
--ignore-case Perform case-insensitive replace operation.
Examples
$ remove-words 'beep! boop!!!' --words='beep,boop'
! !!!To use as a standard stream,
$ echo -n 'beep! boop!!!' | remove-words --words='BEEP,BOOP' --ignore-case
! !!!Notice
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
