"Don't write that stuff until you've tried to live without it and fully understand why you need it." -- James Hague. dale is a tool for iterating over arrays, objects and other values. Why did I write this instead of using underscore or lodash? Well, because I want a very small library that only contains the looping constructs that I always need, no more.

QUESTION
I have a field that has first and last names. Some names include a middle initial, some names include a suffix.
I am trying to find a formula that only pulls the last name regardless of which format it is in.

...ANSWER
Answered 2021-May-24 at 21:12Truth is, working with names can be subject to various edge-cases that will prove a working solution wrong at some point. But for those samples shown I'd use FILTERXML() to "split" these input strings on the spaces and use xpath expressions to filter out those substrings:
Formula in B1:

I have one such problem with my website. I have chapters on the page and in each, there are some modules and theories. In theory, I have the function of reading more so that the text is not just exposed. But the problem arises in that when I have a theory with this function on page 2 or more, the first one works for me and the others do not work as they should and track the first one, and it happens that only the first one works. How do I fix or rewrite it?

Answered 2021-Apr-25 at 00:14First, i have added classes where you have used id's, because id's can't be duplicated, and i have added one small change to your function call, adding current button element as argument.
So, your HTML should look like this now:
QUESTION
I am trying to link our audit history tables against our main data tables in our system.
With the following query:
...ANSWER
Answered 2021-Apr-22 at 03:56You have to apply `RIGHT function with 36 for uniqueidentifier'. As right side, it is uniqueidentifier, in the left side also, you need to cast the datatype as uniqueidentifier to make the comparison working.
You don't need to cast varchar value to uniqueidentifier, as datatype precedence takes care of implicit conversion to higher datatype. Reference datatype precedence

QUESTION
I have two rows of json that I would like to join on id into a single select.
Sample Table A
a [{id: 1, name: "Alice"},{id:2, name: "Bob"}] [{id: 5, name: "Charlie"},{id:6, name: "Dale"}Sample Table B
id age 1 30 2 32 3 20 4 14Desired Output
c [{id: 1, name: "Alice", age: 30},{id:2, name: "Bob", age: 32}] [{id: 5, name: "Charlie", age: 20},{id:6, name: "Dale", age: 14}]I'd like to do something like
...ANSWER
Answered 2021-Mar-23 at 17:19Firstly, this assumes that your JSON is actually valid. None of your elements (id and name) are quoted, so the JSON is actually invalid. Also I assume your expected results are wrong, as Charlie is give the age of 20, but that age belongs to someone with an id with the value 3, and Charlie's has an id of 5.
Anyway, we can can achieve this with a subquery:
QUESTION
I have two instances of a class that I want to swap. Both instances are arrays. I want to swap them using a class method. How do I change/access the instances from within the class method self.collide?
ANSWER
Answered 2021-Mar-15 at 15:40What you are trying to do isn't possible in Ruby, because Ruby does not have "pass by reference" parameters, but always passes by pointer. This means when you make an assignment in a method to a parameter then this doesn't change the value of the variable on the outside:

I have a list called transactions_clean, cleaned up from whitespace etc., look like this:
...ANSWER
Answered 2021-Jan-06 at 11:01When you iterate over your list by for item in transactions_clean: you get items for each list, so indexing them like item[1] would just give you string characters. If the order is always like customer -> sale -> thread_sold, you can do something like this:

Answered 2020-Nov-17 at 06:15You are confusing yourself. You have your solution in edges. There isn't a reason to read the data a second time. For example, you can simply output sorted/unique elements of edges, e.g. the modifications to your code are:

We wrap the entire file in a self-executing anonymous function. This practice is commonly named the javascript module pattern. The purpose of it is to wrap our code in a closure and hence avoid making the local variables we define here to be available outside of this module. A cursory test indicates that local variables exceed the scope of a script in the browser, but not in node.js. This means that this pattern is useful only on the browser. Since this file must run both in the browser and in node.js, we define a variable isNode to check where we are. The exports object only exists in node.js. This is the most succinct form I found to export an object containing all the public members (functions and constants) of a javascript module. Note that, in the browser, we use the global variable dale to export the library. The type function below is copypasted taken from teishi. This is because I needed dale when writing teishi more than I needed teishi when writing dale. Thus, I decided that teishi should depend on dale. And I don't know if I can elegantly cross-reference both libraries, taking just what I need and avoiding circular dependencies.
Distinguish between types of numbers: nan, infinity, integer and float (all of which return number in typeof).
Distinguish between array, date, null, regex and object (all of which return object in typeof).

Values which typeof detects appropriately: boolean, string, undefined, function.
Values which typeof considers number: nan, infinity, integer, float.
values which typeof considers object: array, date, null, regex and object.
