To read line by line of a text area HTML tag with JavaScript, we call split on the text area’s value property.
For instance, we write
const textArea = document.getElementById("my-text-area");
const arrayOfLines = textArea.value.split("\n");
to select the text area with getElementById.
And then we get the text area’s value with the value attribute.
We call split with '\n' to split the value by the line breaks into an array oif lines.
