Question 246312 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – I can't find out how to run replace() correctly

I was trying to run the replace command, but an error occurred:"Uncaught TypeError: variable2.replaceAll is not a function"

Here’s what I tried:

variable2="blah,blah,blah12345";
variable1=variable2.replaceAll(/D/g,'');
console.log(variable1);

I thought varible2 would equal "12345" but instead I got the error: "Uncaught TypeError: varible2.replaceAll is not a function".

    If you are using Typescript, please do the following in your tsconfig.json

    {
    ...,
    "compilerOptions": {
        ...,
        "lib": [
          ...,
          "ES2021.String"
        ]
    }
}

    I tried running your code in Typescript playground and it is showing the same error when running in ES2020 version or lower. The replaceAll method in String is supported from ES2021.

    If you use javascript, you can change the code as follows

    var variable2 = "blah,blah,blah12345";
var variable1 = variable2.replaceAll(/D/g,'');
console.log(variable1);

    Then you can get the results 12345.

    You can just remove the All from replaceAll as the g in /D/galready represents the same functionality – see following snippet which returns 12345

    variable2="blah,blah,blah12345";
variable1=variable2.replace(/D/g,'');
console.log(variable1);
