This is working as designed. There is a longer discussion about this in #14110 if you're curious.

Let's say for some reason you have AppContext whose value has a theme property, and you want to only re-render some ExpensiveTree on appContextValue.theme changes.

TLDR is that for now, you have three options:

Option 1 (Preferred): Split contexts that don't change together
If we just need appContextValue.theme in many components but appContextValue itself changes too often, we could split ThemeContext from AppContext.

function changeArr (arr) {

const suburbs = ['Luctwyche', 'Chemside']

changeArr(suburbs)

console.log('suburbs is ', suburbs)

function changeNumber (thing) {
  thing = thing + 1
}

const myNumber = 123
changeNumber(myNumber)

console.log('my number is ', myNumber)

function changeString (str) {

// --- Directions
// Given an array and chunk size, divide the array into many subarrays
// where each subarray is of length size
// --- Examples
// chunk([1, 2, 3, 4], 2) --> [[ 1, 2], [3, 4]]
// chunk([1, 2, 3, 4, 5], 2) --> [[ 1, 2], [3, 4], [5]]
// chunk([1, 2, 3, 4, 5, 6, 7, 8], 3) --> [[ 1, 2, 3], [4, 5, 6], [7, 8]]
// chunk([1, 2, 3, 4, 5], 4) --> [[ 1, 2, 3, 4], [5]]
// chunk([1, 2, 3, 4, 5], 10) --> [[ 1, 2, 3, 4, 5]]
