Often I want to construct an object with a runtime-generated key.



Here's how I have been doing it:



function make_obj(key, func, val)
 let foo=;
 foo[key] = func(val);
 return foo;



Usage:



make_obj('food', x=>`I like $x`, 'soup'); // food: 'I like soup'


Is there a shorter way to do this?

    You can use [key]: func(val) to create an object literal with a dynamically keyed property.

Function to Return a JSON Like Objects Using VBA Collections and Arrays

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with.

Will my employers contract hold up in court?

Clash Royale CLAN TAG #URR8PPP up vote 8 down vote favorite 2 When I started a new job back in July of 2017, I signed a contract that had the following bindings or restrictions if I was ever to leave the company: Cannot work for a competitor within 25 miles of current companies location for the next two years Cannot offer my services to any organization within 25 miles of current companies location for the next two years Now, when mentioned “my services” this can be related to my profession of website design. This contract seems incredibly binding, 2 years in length, and I’m looking to see if it would actually hold up in an Arizona court. contract employment non-compete arizona share | improve this question edited Aug 7 at 15:35 feetwet ♦ 13.8k 9 37 85 asked Aug 6 at 19:05 Alex S. 46 2 What does your company do and what services do they provide?
