Split a string by the first hyphen in the string

Question

I know the split routine of JavaScript. I've a string in this pattern Employee - John Smith - Director.

I want to split it on the base of first hyphen using JavaScript and it'll seem like:

Source: Employee
Sub: John Smith - Director

Answer 1

I would use a regular expression:

b = "Employee - John Smith - Director"
c = b.split(/\s-\s(.*)/g)
c    
["Employee", "John Smith - Director", ""]

So you have in c[0] the first word and in c[1] the rest.

Answer 2

you can do like

var str = "Employee - John Smith - Director "  
var s=str.split("-");
s.shift() ;
s.join("-");
console.log(s);

Answer 3

var str = "Employee - John Smith - Director "  
str.split("-",1)

Then to split other use this link: How can I split a long string in two at the nth space?

Answer 4

The question is quite old, but I wasn't super satisfied with the existing answers. So here is my staight-forward and easy-to-read solution:

const splitAtFirstOccurence = (string, pattern) => {
  const index = string.indexOf(pattern);
  return [string.slice(0, index), string.slice(index + pattern.length)];
}

console.log(splitAtFirstOccurence('Employee - John Smith - Director', ' - '));
// ["Employee", "John Smith - Director"]
