Split the date! (It's a string actually)

I want to split this kind of String : 

"14:30 - 19:30" or "14:30-19:30"

inside a javascript array like ["14:30", "19:30"]

so I have my variable 

var stringa = "14:30 - 19:30";
var stringes = [];

Should i do it with regular expressions? I think I need an help

Don't forget that you can pass a RegExp into str.split

'14:30 - 19:30'.split(/\s*-\s*/); // ["14:30", "19:30"]
'14:30-19:30'.split(/\s*-\s*/); // ["14:30", "19:30"]

var stringa = '14:30 - 19:30';
var stringes = stringa.split("-");

Try this :

var stringa = "14:30 - 19:30";
var stringes = stringa.split("-");   // string is "14:30-19:30" this style

or

var stringes = stringa.split(" - "); // if string is "14:30 - 19:30"; style so it includes the spaces also around '-' character.

The split function breaks the strings in sub-strings based on the location of the substring you enter inside it "-"

. the first one splits it based on location of "-" and second one includes the spaces also " - ".

*also it looks more like 24 hour clock time format than data as you mentioned in your question.

.split is probably the best way to go, though you will want to prep the string first. I would go with str.replace(/\s*-\s*/g, '-').split('-'). to demonstrate: 

var str = "14:30 - 19:30"
var str2 = "14:30-19:30"
console.log(str.replace(/\s*-\s*/g, '-').split('-')) //outputs ["14:30", "19:30"]
console.log(str2 .replace(/\s*-\s*/g, '-').split('-')) //outputs ["14:30", "19:30"]

If you know that the only '-' present will be the delimiter, you can start by splitting on that:

let parts = input.split('-');

If you need to get rid of whitespace surrounding that, you should trim each part:

parts = parts.map(function (it) { return it.trim(); });

To validate those parts, you can use a regex:

parts = parts.filter(function (it) { return /^\d\d:\d\d$/.test(it); });

Combined:

var input = "14:30 - 19:30";
var parts = input.split('-').map(function(it) {
  return it.trim();
}).filter(function(it) {
  return /^\d\d:\d\d$/.test(it);
});

document.getElementById('results').textContent = JSON.stringify(parts);
<pre id="results"></pre>

You can just use str.split :

var stringa = "14:30 - 19:30";
var res = str.split("-");
