How to remove a word from a string and all the other subsequent ones?

Question

I have a string url and I need to withdraw the word Dashboard and all subsequent characters (including bars).

Example:

"Algumcoisa/Dashboard/Outracoisa/Maisalgumacoisa"

I want you to stay like this:

"Algumacoisa/"

I’ve tried to:

pathname = window.location.pathname
url = pathname.replace("/Dashabord.*/",'')

I can always test that code on regex like the https://www.regextester.com/99144, but I can never accomplish replace.

With regex (I don’t particularly like it) works with this essential modification which is to remove the double quotes that surrounds your test, because there it tests a text the way it is written and not really the word you want to search and delete from it all the rest, example:

pathname = "Algumcoisa/Dashboard/Outracoisa/Maisalgumacoisa"
url = pathname.replace(/Dashboard.*/,'');
console.log(url);

For me it is better to use a more readable form of code, first search with index the position that starts the search Dashboard and then with substring returns part of that text, example:

const url = "Algumcoisa/Dashboard/Outracoisa/Maisalgumacoisa";
const index = url.indexOf("Dashboard");
const newUrl = url.substring(0, index);
console.log(newUrl);

^References:

• Javascript - regex

  Regular expressions are patterns used to select combinations of characters in a string. In Javascript, regular expressions are also objects. They can be used with methods exec and test of the object Regexp, and with the methods match, replace, search, and split of the object String.

• Javascript - indexof

  The index() method returns the first index where the element can be found in the array, returns -1 if it is not present.

• Javascript - substring

  The substring() method returns a subset of a string between an Dice and another, or to the end of the string.
