Not able to replace sub string having bracket from string array in typescript/javascript

Question

I have a string e.g. My column name is Start Date (GMT)

I want to replace Start Date (GMT) portion with start_date.

I am trying to do it like:

    let a= "My column name is Start Date (GMT)";
    let b = "Start Date (GMT)";
    let str = new RegExp(b,"g");
    console.log(a.replace(str,"start_date"));

With same code I am able to replace the string with desired value if brackets are not there, but since bracket '(' is there it is not able to identify the string and replace it.

So, as always, just escape the literal pattern string, `let str = new RegExp(b.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&'),"g");` — Wiktor Stribiżew, Oct 01 '18 at 12:34

This would work.

while loop will run till all the Start Date (GMT) are replaced by start_date.

let str = "My column name is Start Date (GMT) Start Date (GMT)";

while(str != str.replace('Start Date (GMT)', 'start_date')) {
  str = str.replace('Start Date (GMT)', 'start_date');
}

console.log(str);

I doubt OP wants to use a string replace, the `g` modifier hints at the OP intention to replace multiple occurrences. – Wiktor Stribiżew Oct 01 '18 at 12:24
Actually i want it for multiple occurrence only. Above code snippet was just example. – Vivek Pandita Oct 01 '18 at 12:30
I have updated the code – vrintle Oct 07 '18 at 06:13
