You use these functions when you want to find values based on the value in a corresponding cell. Thanks to the newish dynamic array function XLOOKUP (), you now have more power and less confusion.

In the above example, the integer array named rentedArray will have 10 elements; i.e., you can store 10 integer values in the array. You can also write the preceding code as shown below.

Stay tuned There are several new dynamic array functions and over the next few months, we’ll cover several of them. Next up, we’ll be using SEQUENCE () to return the top n values in a data set.

Using the Java array length for size To determine the size of an array in your code, you need to use the Java array’s length property field. Just make sure the array is not null, and don’t confuse ...
