lodash _.contains one of multiple values in string

Question

Is there a way in lodash to check if a strings contains one of the values from an array?

For example:

var text = \'this is some sample text\';
var values         


        

Answer 1

Another solution, probably more efficient than looking for every values, can be to create a regular expression from the values.

While iterating through each possible values will imply multiple parsing of the text, with a regular expression, only one is sufficient.

function multiIncludes(text, values){
  var re = new RegExp(values.join('|'));
  return re.test(text);
}

document.write(multiIncludes('this is some sample text',
                             ['sample', 'anything']));
document.write('
');
document.write(multiIncludes('this is some sample text',
                             ['nope', 'anything']));

Limitation This approach will fail for values containing one of the following characters: \ ^ $ * + ? . ( ) | { } [ ] (they are part of the regex syntax).

If this is a possibility, you can use the following function (from sindresorhus's escape-string-regexp) to protect (escape) the relevant values:

function escapeRegExp(str) {
  return str.replace(/[\-\[\]\/\{\}\(\)\*\+\?\.\\\^\$\|]/g, "\\$&");
}

However, if you need to call it for every possible values, it is possible that a combination of Array.prototype.some and String.prototype.includes becomes more efficient (see @Andy and my other answer).
