For example, i have these strings:
I want to remove the URL's protocol, variant-, and domain using JS .replace() and regex, so the strings will be:
color
size
type
How to do it? I've tried it with the following code but it didn't work:
.replace("http://variant-","").replace("https://variant-","").replace(/^.[a-zA-Z]*/,"")
Well, there are multiple ways to do this. One of the easiest one could be using positive look behind approach with this regex:
/(?<=\-)\w+/gm
This will only match characters in your URL once they followed by - sign.
So the final output will be something like this:
const arr = [
"https://variant-color.com",
"http://variant-size.biz",
"http://variant-type.ca"
]
const newArr = arr.flatMap(item => {
return item.match(/(?<=\-)\w+/gm)
})
console.log(newArr)
String#match is available through every javascript library.
