The ARRAY_CONSTRAIN function in Google Sheets allows you to constrain an array to a certain size or shape. This can be useful when you want to ensure that the data in your array is organized in a certain way, or when you need to restrict the size of your array for performance reasons. To use the ARRAY_CONSTRAIN function, simply enter it into a cell alongside the array you want to constrain. The function will then automatically update the size and shape of the array to match the constraints you specify.
ARRAY_CONSTRAIN constrains an array to have a specific length. It takes two arguments: the number of elements in the array, and the array itself. The following code snippet creates an array with five elements:
var myArray = ARRAY_CONSTRAIN(5, [1, 2, 3, 4, 5])
If you try to add a sixth element to myArray, it will be automatically truncated.
ARRAY_CONSTRAIN allows you to constrain the size of an array. You can use it to set a lower and upper bound for the number of elements in the array. You can also use it to set a lower bound for the number of unique values in the array.
There are a few occasions when you should not use ARRAY_CONSTRAIN in Google Sheets. First, you should not use ARRAY_CONSTRAIN when you are trying to create a formula that refers to a range of cells on a different sheet. Second, you should not use ARRAY_CONSTRAIN when you are trying to create a formula that refers to a range of cells that is not in a contiguous block. Finally, you should not use ARRAY_CONSTRAIN when you are trying to create a formula that refers to a range of cells that is not in a single column or row.
ARRAY_CONSTRAIN is a formula in Google Sheets that allows you to constrain an array to a certain size. There are similar formulae that you can use to achieve the same results. These include:
SMALLEST: This formula will return the smallest value in an array.
LARGEST: This formula will return the largest value in an array.
SUM: This formula will return the sum of all the values in an array.
AVERAGE: This formula will return the average of all the values in an array.
