I wonder why the question was downvoted? Sure it may be a dupe, but it's a well asked question — musefan, Apr 11 '18 at 09:10
To be clear, do you **have** to use `split`? Or are you OK to use regex with replace function? — musefan, Apr 11 '18 at 09:11

You can avoid using split and splice. Simply, use replace in global scope

USING REPLACE

var str = 'my name , is , shahab';
var res = str.replace(/\, /g, '');
console.log(res);

USING SPLIT AND JOIN

let str = "my name , is , shahab";
var res  = str.split(',').join('');
console.log(res);

Why are you escaping the comma in your regex? It's not a metacharacter. – Robby Cornelissen Apr 11 '18 at 08:57

Question specifically ask for using split and splice, perhaps you should clarify with the OP if regex is acceptable first – musefan Apr 11 '18 at 08:57

@musefan I know that but since I am giving answer to help the OP and optimize his code. I preferred to give this. – Ankit Agarwal Apr 11 '18 at 08:58

@AnkitAgarwal: And what if the OP is not permitted to use regex? Then your answer is useless... best to check first rather than presume – musefan Apr 11 '18 at 08:58
@musefan Where in the question does it specifically ask that? – Robby Cornelissen Apr 11 '18 at 08:59

@RobbyCornelissen: The title... you know, the big text at the top... – musefan Apr 11 '18 at 08:59
@RobbyCornelissen and musefan. I have edited my answer with both. OP can check for both. – Ankit Agarwal Apr 11 '18 at 09:00
@AnkitAgarwal: Fair enough... though I personally don't like having to click a link to see 3 lines of code, but that's just my opinion – musefan Apr 11 '18 at 09:02
@musefan I somehow overlooked that. Thanks for your kind and clarifying remark. – Robby Cornelissen Apr 11 '18 at 09:02
@RobbyCornelissen: No problem... just wanted to help you locate exactly where it was – musefan Apr 11 '18 at 09:02
splice do not make sense. Split and join will make proper sense. What do you say? – Ankit Agarwal Apr 11 '18 at 09:03
@musefan Your efforts are sincerely appreciated. – Robby Cornelissen Apr 11 '18 at 09:03
@RobbyCornelissen what do you think the answer should be upvoted or downvoted? – Ankit Agarwal Apr 11 '18 at 09:18

You can split by ,(comma) into arrays and then join them

let alpha = "my name , is , shahab";
alpha = alpha.split(",").join("");
console.log(alpha);

You can either call .replace(‘,’, ””) twice or preferably write your own replaceAll function using regular expressions:

function(search, replacement) {
    return this.replace(new RegExp(search, ‘g’), replacement);
}
