Use the following code:-

const path = require('path');
const extension= path.extname(params.strdocumentname);
const name= params.strdocumentname.replace(extension,"(" + results.rows[0].arrayfilecount+ ")");
const newName = name + extension;

Hope it helps Thanks

I think your params.strdocumentname contains the extension of the file also. Try this code;

let [fileName, extension] = params.strdocumentname.split('.');
let NewName= fileName + "(" + results.rows[0].arrayfilecount+ ")." + extension;
strdocumentname = params.strdocumentname = NewName;

see working fiddle

let mockFileName = "abc.png"
let mockArrayCount = '1'

let [fileName, extension] = mockFileName.split('.');
let NewName= fileName + "(" + mockArrayCount+ ")." + extension;

console.log(NewName)
alert(NewName)
