substring replace from string in javascript

Question

This is string

chat('star_comment','11211967','17','HF00008','MLR51101639100ICI100','B19','0','2020');

i want to replace it to like this in javascript:

chat('star_comment','11211967','17','HF00008','MLR51101639100ICI100','B19','RO_RX','2020');

my code is like this:

var str = "chat('star_comment','11211967','17','HF00008','MLR51101639100ICI100','B19','0','2020')";
check = "0";
var res = str.replace("/\/"+check+"\//", "RO_RX");

but this is not working

str.replace("'0'", "'RO_RX'") Why not this?

Simplify the replacement and put the single quotes in the selector (check) direcctly

var str = "chat('star_comment','11211967','17','HF00008','MLR51101639100ICI100','B19','0','2020')";
let check = "'0'";
var res = str.replace(check, "'RO_RX'"); 
console.log(res);
