Is it possible to use the String.replace() method in JavaScript to replace any character with a line feed symbol? For example:
newString = oldString.replace(/x/, "linefeed character (\n)").

Absolutely:
let initialText = "Example<br>secondline<br>thirdline";
let regexPattern = /<br\s*[\/]?>/gi;
let updatedText = initialText.replace( regexPattern, function converter(match){
let newLineChar = '\n';
return newLineChar;
} );
alert(updatedText);
Absolutely, it is possible to include newline characters in the replacement value of the .replace(...) method without any issues. Just treat it like any other string. Here's an example:
button.onclick = function() {
// Remember to use the /g flag if you want to replace all occurrences.
textarea.value = textarea.value.replace(/NL/g, '\n');
}<textarea id="textarea">fooNLbarNLbaz</textarea><br />
<button id="button">Replace NLs with New Lines</button>If you plan on using this within a standard text node in HTML (not inside <textarea> or <pre> tags), keep in mind that white space, including newlines, may collapse into a single space character by default. To control this behavior, utilize the CSS white-space property.
