# Building a field in the find the number game in JavaScript

In the previous lesson, I described the `build` function, which will receive as parameters a reference to the playing field and a two-dimensional array with random numbers returned by the `prepare` function.

Our `build` function will form table cells filling them with numbers from the array. For example, using our functions, we can create an initial `2` by `2` table like this:

`build(field, prepare(2));`

Here is a draft of the described function:

`function build(field, arr) { }`

Write an implementation of this function.

Modify your function to return an array of generated table cells:

`let cells = build(field, prepare(2)); console.log(cells);`

Modify your function to clear the table's `textContent` before creating a field in it.
