I have a keyword string that contains at least 1 wildcard letter; "?". Each "?" represents a single lowercase letter between a-z. I need to search through an array of strings to find which letters match the keyword.
let input = ["happy", "have", "harvest", "harmonica"]
let keyword = "ha???"
result = "happy"
I've tried to replace the wildcard letter ? with regex, but it does not seem to work because it would return "ha/([a-z])+/g" and would not compare like I wanted it to.
I also tried to just replace ? with "", but obviously it would match all of the items so it doesn't work.
Is there any suggestions?
You could just replace ? with [a-z], and add start and end of string anchors (^ and $) to your regex. For example:
const input = ["happy", "have", "harvest", "harmonica"]
const keyword = "ha???"
const regex = new RegExp('^' + keyword.replace(/\?/g, '[a-z]') + '$')
const result = input.filter(w => regex.test(w))
console.log(result)
