Powerquery M Code Language Part4

Data cleaning and structuring using Powerquery M Code

What you'll learn
This is M code Part4 and this course will provide the information on List Generate and List Buffer type of functions
This is an advance level and one should already know M code very well, especially about Lists and table functions.
You will learn how to use recursive functions like a loop which can take different inputs every time it runs.
Advance functions for data analysis and data strucuring.
Requirements
Knowledge of M code is required. This is Part4. If you are new, please check three parts before this.
Description
Please note that if you have seen previous Parts of M code series then only it will be a fun and clarity. This part 4 is not for beginers . If you know how to use lists, functions and how to write syntax in m code, pls go ahead and take this course.M code Part4 is talking about List.genrate function and how to use it as a function in real life plus other functions also in focuss.Introducing the list generate function in M code.What is a list generate function and how its parameters workWhat is the initial parameter, what is the conditional parameter and execution parameter?How to use list generate function using two variables or even more than two variables and how to know the number of variables we have to use.We have started from a beginning and have tried to explain the Concept of this function is clear step by step.There is a 4th hidden parameter which students never see and infact , even they know they don't know how to use it and what is the use of same.What is the role of an optional parameter in list generate function and how does it work.How to know where do we use square brackets , commas especially in a code where it is using data.How to convert list generate into a function which takes inputs and then connect it with the real dataTable sort function in real dataTable select column functionTable select rows functionHow to combine two columns in a sequence using Mcode interface.How to approach a problem - with function and without function - which one is better
