Syntax

fill(predicate, value)

Parameters

Param	Description
`predicate`	Function: A predicate function `({ row, col, value }) => boolean` selecting cells to fill
`value`¹	Any: A valid JavaScript value

If value is a function, it is evaluated per cell. Use Quadrille.factory(({ row, col }) => new Object(...)) to generate a new object per cell. For display routines, use a plain function like ({ row, col, options }) => { ... }. See options for available parameters. ↩︎
