Reversing = Sign Changes Logic

How come when I reverse the logic here and make it const myArray.pop() = removedFromMyArray, then I get an error message on the question

Your code so far

// Setup
const myArray = [["John", 23], ["cat", 2]];

// Only change code below this line

const removedFromMyArray = myArray.pop()

Challenge: Basic JavaScript - Manipulate Arrays With pop()

Link to the challenge:

For the assignment operator = the order matters

On the left goes the variable holding the value and the right goes the expression that creates the value
