Do NOT use .split(''). You'll get weird results with non-BMP (non-Basic-Multilingual-Plane) character sets.. Reason is that methods like .split() and .charCodeAt() only respect the characters with a code point below 65536; bec. higher code points are represented by a pair of (lower valued) "surrogate" pseudo-characters.

Mar 16, 2009 · @BrodaNoel you're correct that's the one major caveat of the first code example. In that particular case it's best to use a character that is safe to split on, in my example the intent was to replace the , so it was "safe" but it certainly is something to be mindful of.

May 12, 2013 · I'm trying to split a multidimensional array of strings using a string separator, but I don't yet know how to iterate over a multidimensional array without using multiple for-loops. var theArray = [["Split,each"],["string, in"],["this, array"]]; As far as I know, it isn't possible to apply the string.split(",") method to a multidimensional ...

I would like to first split the string by its slashes (/) and run a loop through the different values and do stuff to those elements on my page. To give an idea of what I need to achieve, I have given this example which is a mix of ASP & JS - it's the only way I can possibly describe it (and show that I've had an attempt) :)

If separator is a regular expression that contains capturing parentheses, then each time separator is matched, the results (including any undefined results) of the capturing parentheses are spliced into the output array. [reference) So: var stringArray = str.split(/(\s+)/); ^ ^ // Output:

split() method in JavaScript is used to convert a string to an array. It takes one optional argument, as a character, on which to split. In your case (~). If splitOn is skipped, it will simply put string as it is on 0th position of an array.

Jan 2, 2015 · Array.prototype.map: "The map() method creates a new array populated with the results of calling a provided function on every element in the calling array". Source : developer.mozilla.org . array.map(Number) : This call means the first received argument will be automatically converted into number and results in the same as if you explicitly ...

Dec 25, 2015 · At this point, pieces is an array and pieces.length contains the size of the array so to get the last element of the array, you check pieces[pieces.length-1]. If there are no commas or spaces it will simply output the string as it was given.

I had a similar issue, but more complex as I needed to transform a CSV file into an array of arrays (each line is one array element that inside has an array of items split by comma). The easiest solution (and more secure I bet) was to use PapaParse which has a "no-header" option that transform the CSV file into an array of arrays, plus, it ...
