QUESTION
I'm creating a search box that allows you to search for different companies. I'd like the search box to perform a 'contains' search. For example, let's say that I want to look up the company ExxonMobil Oil Corp. Typing in any of the following should include the company in the list of results (this isn't exhaustive):
- oil
- corp
- oil corp
- exxonmobil
- exxonmobil oil
- exxonmobil oil corp
The words don't have to be complete, just to be clear. The phrase 'oil co', for instance, should still bring up a result.
Typing in 'exxonmobil corp', however, will not bring up the company as a result since 'corp' does not immediately follow 'exxonmobil' in the company's name.
Is there a go-to method for implementing this type of search, keeping time efficiency in mind? In my case, there can be thousands of companies to search through. And I'd like to be able to display the list of results on the fly as the user is typing into the search box.
I'm aware of the trie data structure, but from what I've read, it seems to work best for 'starts with' searches. So it wouldn't match searches like 'oil corp', 'oil', or 'corp' with ExxonMobil Oil Corp. Perhaps there's a way to tweak the trie to do as I want, but I'm just not sure if that's the best way to go.
Thank you for the responses. A few of you suggested looking into String.prototype.includes(). I gave that a try, and it does seem to work well with no performance issues.

QUESTION
Is there an official way to pass the head of a pipe function as a normal function argument? Like how you can modify functions with .call
and .bind
, I want to modify String.prototype.includes so that it looks like includes('a')('acd')
. Basically, I want a function that makes it's first argument, say 'abc', the String instance in String.prototype.includes('a')
He'res my best attempt... that doesn't work, because, why would it
['abc'].some(String.prototype.includes('b'))
Basically I want a cool confusing version of this
x => x.includes('b')
Is there a version of call, bind or depipe method in Javascript that does what I need?

...ANSWER
Answered 2021-May-27 at 16:21There is no built-in way to do this. Ignoring libraries like ramda/lodash.fp that let you do this through helper methods - you would need to implement your own helper. As the arguments are "reversed" you cannot simply eta-reduce (avoid the extra lambda):

Please let me know if you understand why my nuxt app fails on internet explorer. In the part of my code, I had used array.includes() which I realized is not supported by IE and removed but still not working. I do use forEach loops which should be supported by IE11

Answered 2020-Jul-07 at 09:26IE doesn't support forEach
for HTMLCollection.
You could add the following polyfill in your script to polyfill forEach
then it can be used for both NodeList and HTMLCollection in IE:
QUESTION
Roy wanted to increase his typing speed for programming contests. His friend suggested that he type the sentence "The quick brown fox jumps over the lazy dog" repeatedly. This sentence is known as a pangram because it contains every letter of the alphabet.
After typing the sentence several times, Roy became bored with it so he started to look for other pangrams.
Given a sentence, determine whether it is a pangram. Ignore case.
It should return the string pangram if the input string is a pangram. Otherwise, it should return not pangram.
SAMPLE INPUTS
We promptly judged antique ivory buckles for the next prize
// pangram
We promptly judged antique ivory buckles for the prize
// not pangram (missing letter x)

Answered 2020-May-11 at 06:49Your regular expression is wrong. It will only check if the string contains one letter from a
to z
. You also aren't testing it properly - String.prototype.includes
checks for substrings being included in the larger string, not for regular expression validation.
If you want to test whether a regular expression matches a string, use .test
. To check that all letters exist in a string with a regular expression, you'll have to repeat (?=.*a)
for every character, eg:

QUESTION
I have the following code which filters an array by tags (specifically 2 tags). It works well with word strings but I would like to add the ability to use some sort of wildcard. For example to filter all tags that start with "-"
(my attempt at grouping the tags). Using this string here doesn't work. I have also tried using a regular expression eg. /^-/
but that doesn't work either.
I have discovered that Array.prototype.includes()
differs from String.prototype.includes()
in that it only captures whole "words" so that probably explains why it's not working but was I wondering if there was some way to do this?
ANSWER
Answered 2020-Jan-07 at 11:35As others mentioned, you cannot use regex with Array.includes()
. The simplest way would be to use a some()
or every()
(depending on what do you want to achieve) instead:
