Is there a way to ensure my text has a trailing newline using just one regex expression instead of two? Currently, I achieve this by using two separate regex expressions:
myString.match(/[^\S\r\n]\n/) || myString.match(/[^\S\r\n]$/)

Here are two different methods to identify trailing horizontal whitespace in a string, one utilizing regular expressions and the other without:
var words=['apple', 'banana '];
// using trimEnd() function to check for trailing whitespace
words.forEach(word => {
if (word.length > word.trimEnd().length)
console.log(word + " contains trailing white space");
});
// regex method that detects space or tab at the end of each line
const pattern = /[ \t]$/m;
words.forEach(word => {
if (pattern.test(word))
console.log(word + " has trailing whitespace");
