The For Objects

Import Weave.ForPairs, Weave.ForKeys, or Weave.ForValues from the Weave module.

local Weave = require(ReplicatedStorage.Weave)
local ForValues = Weave.ForValues
local ForKeys = Weave.ForKeys
local ForPairs = Weave.ForPairs

Weave has functions for turning Weave Value or Computed into an Instance

local playerNames = Value.new({ "Kreekcraft", "Sleitnick" })

ForValues(playerNames, function(name)
    return Attach(TextLabel:Clone()) {
        Text = name,
        Parent = screenGui
    }
end)

✨ For function update state automatically ✨

playerNames.set({ "Sleitnick" }) -- "Kreekcraft" TextLabel is Destroyed

For functions turn Weave state into UI.

Usage

For functions take

1. A Weave Computed or Value table.

2. A function that returns an Instance

local playerNames = Value.new({"Elttob", "boatbomber", "thisfall", "AxisAngles"})

ForValues(playerNames, someFunction)

Where someFunction

• Receives a value from the table

• Returns an Instance

ForValues(playerNames, function(name)
    local textLabel = TextLabel:Clone()

    return Attach(textLabel) {
        Text = playerName,
        Parent = ScreenGui
    }
end)

Over the next few pages, we'll take a look at three state objects:

• ForValues: values in a table.
• ForKeys: keys in a table.
• ForPairs: keys and values in a table.
