# Function to start the find the number game in JavaScript

In the previous lesson, you had to make a function to activate cells. With its help, we can already start the game process:

`let field = document.querySelector('#field'); let size = 2; // an initial field size activate(build(field, prepare(size)));`

However, it would be better to move the start of the game into a separate function:

`let field = document.querySelector('#field'); start(2); function start(size) { activate(build(field, prepare(size)), size); }`

Implement the described beginning of the game. Try to create fields of different sizes by passing different parameters to the `start` function.
