- Who Get The Lambda() Helper functions?
A quick and easy way to calculate each column or row of a table or array is with the ByCol() or ByRow() functions. For many people these two functions might be the most immediately useful of the Lambda() helper functions. Let’s say you have a table of data for your monthly expenses, and you’re concerned in finding out how much you spend monthly. Un...
Map() makes a clone or copy of a source table/array changing each cell value according to the Lambda() function. That’s possible now with a series of formulas referencing the original table in a matching table. Map() means the whole thing can be done with a single formula which changes as the source table does. The examples Microsoft gives are good...
Reduce() takes a table or array and does a calculation on all the values to come up with a single result. Each cell value is passed to the Lambda function in turn. The temporary result (between each Lambda() calculation) is held in an accumulator variable. Microsoft’s Map() example is good, we’ll just reduce it a little more … pun intended. The res...
Reduce() calculates a single value after processing all the cells in the table/array. The interim steps of the calculation aren’t shown. Scan() returns an array showing the result of each step as the Lambda() calculation works on each source cell. In other words, it shows a running total or calculation. Here’s another v. simple example of a running...
MakeArray does as it says on the label, it makes a new array based on the values from a Lambda() function. The Lambda() function is called for each cell in the new array. There’s no accumulator so each calculation is separate. Here’s a variation on Microsoft’s example to make a randomize list of (Goonish) names. =MAKEARRAY(10,1,LAMBDA(row,col,CHOOS...
