How to list array inside a javascript alert

Question

I have an array of strings, I want to display the content with some html tags in the alert level. I tried this:

array = ["toto", "titi"]
alert("*" + array.join('\n'))

but the problem here, I got only the first line with *. how can I resolvr this probleme to show all the lements with * in the begining ?

Answer 1

Array.map()

You should use map method to create a new array populated with each element having * prefix.

const array = ["foo", "bar"];

alert(array.map(value => `*${value}`).join('\n'));
