Remove Words

Remove a list of words from a string.

Installation

npm install @stdlib/string-remove-words

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 );
