Remove second part of string with split() [duplicate]

Question

I have a variable with a string, let's say this one, which I then display on a page on the site:

let value = "qwe asd — bensound summer";

document.getElementById("text").innerHTML = value;

And I want to remove its second part when displaying this line on the page bensound summer along with a dash —.

And in order to receive only the first part, which is before the dash, when displayed on the page, in the form: qwe asd.

I read about str.split() but didn't find anything like it and didn't quite understand how it all works.

Does this answer your question? Get Substring between two characters using javascript — Tobias S.

Use the split method

let value = "qwe asd - bensound summer";

value = value.split('-')[0] // 

document.getElementById("text").innerHTML = value;

I discovered that the symbol you are using is not the same try using this "—" == "-" in the console you'll get false

You can use it like this:

let value = "qwe asd — bensound summer";
let splittedString = value.split("-");

document.getElementById("text").innerHTML = splittedString[0];

Hope, it helps!!
