How to get project folder path in visual studio code extension

Question

I am trying to get project folder path in visual studio code extension but very difficult to find the answer. My code is not working. I do not know it is possible or not. I have checked in google no one answer for this question. Anyone know about this please help me to find the answer.

extension.js:

var vscode = require("vscode");
var path = require("path");

exports.activate = context => {
const findPath = 
vscode.commands.registerCommand('extension.search', () => {

   let findprojectfolderPath = vscode.workspace.uri.fsPath; // Not working

   console.log(findprojectfolderPath);

});
}

I would like to update Pushprajsinh Chudasama's answer as vscode.workspace.rootPath is now deprecated. It is being replaced by vscode.workspace.workspaceFolders which returns an array of WorkspaceFolders | undefined. To retrieve the path to all your workspace folders, you may now use:

vscode.workspace.workspaceFolders?.map(folder => folder.uri.path)
