How to use String.prototype.split() and Array.prototype.join() In Javascript
Using String.prototype.split() and Array.prototype.join(), the approach splits the string by line breaks using a regular expression. Then, it joins the resulting array elements back into a single string, effectively removing all line breaks.
Example: In this example The function removeLineBreaks() correctly eliminates all line breaks from the input string using split with a regular expression, then joins the substrings.
function removeLineBreaks(str) {
return str.split(/\r?\n|\r/).join('');
}
const stringWithLineBreaks =
"Hello\nworld!\nHow are\nyou?";
const stringWithoutLineBreaks =
removeLineBreaks(stringWithLineBreaks);
console.log(stringWithoutLineBreaks);
Output
Helloworld!How areyou?
How to remove all line breaks from a string using JavaScript?
Line breaks in strings vary from platform to platform, but the most common ones are the following:
- Windows: \r\n carriage return followed by a newline character.
- Linux: \n just a newline character.
- Older Macs: \r just a carriage return character.
There are two methods to accomplish this task. One of the ways is by using a traditional programming loop and visiting every character one at a time. Another is using Regular Expressions.
