JavaScript Split empty string should return empty array split empty string python,split empty string java,split empty

If I use

''.split(',')

I get [''] instead of an empty array [].

How do I make sure that an empty string always returns me an empty array?

Answer:1

You can use splice()

''.split(',').splice()
//[]

this example works for your problem:

function returnArr(str){
  return !str ? [] : str.split(',')
}

returnArr('1,2,3')
// ['1','2','3']
returnArr('')
//[]
Answer:2

split() always try to split into pieces, so you can try:

l='';
list=(l=='')?[]:l.split(',');

always works for

l='p,q,r';
list=(l=='')?[]:l.split(',');

Also you can write a new split method like:

String.prototype.split2 = function (ch) { 
   return (this=='')?[]:this.split(ch) 
}

So tou can try:

''.split2(',');         //result: []
'p,q,r'.split2(',');    //result: ['p','q','r']
Answer:3

try with this

  r=s?s.split(','):[];
