## Uncaught TypeError: visitorIDs.push is not a function

I’m trying to build an array of the ID’s of the users in a peoplePicker Field by using push. So far.. I’m not having much luck as I’m getting this error “Uncaught TypeError: visitorIDs.push is not a function”

My code is below. I appreciate any suggestions/pointers:

 // Get information about all users.             var users = peoplePickerVisitors.GetAllUserInfo();             var userInfo = '';             for (var i = 0; i < users.length; i++) {                 var user = users[i];                 for (var userProperty in user) {                     userInfo += userProperty + ':  ' + user[userProperty] + '<br>';                 }             }              var userloginbase = users[0].Key;             var userlogin = userloginbase.split("\");              var context = SP.ClientContext.get_current();             var newUser = context.get_web().ensureUser('xxxxxxx\' + userlogin[1]);             context.load(newUser);             context.executeQueryAsync(function () {                 },                  function (sender, args) {                 });                 // pause for a second to let the async ensure user complete.                 setTimeout(function() {                      getAssignedToUserIdByEmail(users[0].EntityData.Email);                       visitorIDs = ResolvedToUser.Id;                     visitorIDs.push(ResolvedToUser.Id);                  }, 100);          };

## Coefficients in cost function in A-star

I’d like to expand on this question :

https://stackoverflow.com/questions/52420788/why-does-the-a-star-algorithm-need-gn

Dijkstra’s algorithm uses cost function $$f(n) = g(n)$$ whereas A* uses cost function $$f(n) = g(n) + h(n)$$, with $$g(n)$$ being the cost of the path from the start node to node $$n$$, and $$h(n)$$ is a heuristic function that estimates the cost of the cheapest path from node $$n$$ to the goal.

It is clear from the linked question’s answer that A* needs its $$g(n)$$ function in the cost function. My question however is the following. Can one use the cost function :

$$f(n) = \alpha g(n) + (1-\alpha)h(n)$$

for some alpha $$0<\alpha<1$$ ?

I ask because in some cases I observed it can be much faster to prioritize (through a coefficient) estimated cost over already traversed cost. I am not sure however if this still results in an optimal path?

EDIT : multiplying the heuristic $$h(n)$$ by some alpha $$0<\alpha<1$$ is allowed, since this operation still underestimates if $$h(n)$$ already did (which is necessary to obtain the resulting optimal path). I am more concerned about the multiplying of $$g(n)$$.

## Adding a search function to a lookup column?

Situation:

• I have a list and a library.

• The list has a lookup column that allows you to choose multiple documents from the library.

Problem:

• The library has several hundred documents, so it’s very difficult to find the right document(s) to add to the list item.

Is there any way I can implement a search function above the list of documents so the list filters dynamically as I start typing the beginning of the document reference?

I have yet to find a proper solution to this problem and I need to avoid using SharePoint Designer for maintenance reasons if at all possible.

## Call a function from a bash script

I have a function in a specific installed program on my Ubuntu machine which is installed in /usr/local/MYPROGRAM/bin/myfn and when I try using myfn in my bash script mybashscript.sh it gives an error saying that the myfn command is not found but if I call myfn from a normal terminal window it works fine since it’s found in the ~/.bashrc file, so I wonder how I can call myfn from my bash script mybashscript.sh?

I tried the solutions available online but I still see the error.

Solutions I tried so far:
