How to get a Substring JAVASCRIPT? [duplicate]

Question

I need to iterate over strings that are inside an array, to get a sub-string in each string.

Substrings are between "()"

Something like this..

let myArray = ["animal(cat)", "color(red)", "fruits(apple)"];

//return
//'cat','red','apple'

How I could do that?

What have you tried? developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… might contain something which would help you. Or maybe regular expressions would be better. Either way, this is not a free write-my-code service. We'll help you, we won't do it for you. Thanks. — ADyson

You can do this using substring and lastIndexOf functions.

let myArray = ["animal(cat)", "color(red)", "fruits(apple)"];

myArray.forEach(function(e){
    console.log(e.substring(e.lastIndexOf("(") + 1, e.lastIndexOf(")")))
})
