from string var str = "Hello rn World"; // Outputs "Hello World" str = str.replace(/r?n|r/g, '');
The code line is using the replace method to remove line breaks from a string. The regular expression /r?n|r/g matches any type of line break, and the empty string ” replaces each match with nothing.
Tips to work with lines
Second, keep in mind that lines can be divided into two types: normal lines and comment lines. Normal lines are simply lines of code that are not comments. Comment lines, on the other hand, start with a hash symbol (#) and are used for commenting out code sections. You can identify comment lines by looking for a line that starts with a double slash (//).
Finally, remember that you can use the line number property to reference specific lines in your code. This is especially useful when debugging your code.
