Count the number of lines in a string in JavaScript
Question:
How to count the number of lines in a string using JavaScript? Answer:
const getLineCount = (text) => {
if (!text) {
return 0;
}
return text.split(/\n/).length;
}Description:
The split() method divides a string into a list of substrings, puts these substrings into an array, and returns the array. The division is done by searching for a pattern (separator); where the pattern is provided as the first parameter in the method's call. The separator can be a simple string or it can be a regular expression.
To get the line numbers in a string, count the number of newline characters.
