const vunjs = new VunJS() // Creating new object from our class.

// Setting up database path.
vunjs.SetupDatabase('./database/') 

// Creating our table named users as JSON file.
vunjs.CreateTable('users') 

// Inserting new data to users database as JSON object.
vunjs.InsertData('users', { name: "test", surname: "blabla" }) 

// Searching data if any of it mathches our JSON object and printing it out as an array.
vunjs.SearchData('users', { surname: "blabla" }, (data) => {
    console.log(data)
}) 

// Delete all data in users table if contains JSON object.
vunjs.DeleteData('users', { name: "test" }, vunjs.DataCount('users')) 

// Changing our name from test to Testv2
vunjs.UpdateData('users', 1258111, { name: "Testv2" })

NOTE

Do not try to insert any unique ID's to database you insert data into. It creates a unique ID and adds it into your JSON object.
