I want to loop through an array of objects using *ngFor
For more explanation see below :
[
{sn: 'N300W150726', merchantName: ' test''}
{sn: 'N300W150726', merchantName: 'alex', }
{sn: 'N300W150726', merchantName: 'alexa',}
]
Once I want to pass clicked data due the function I got an error
my function shown below
<button nbButton (click)="getTpeByUser(item.sn)">
{{ item.merchantName}}
</button>
Do you see totally nothing? Then check toggle variable. Is the list not showing? Then check the nameUsersByType Array. BTW: the array elements are not separated by commas. Is this true? Then look there for your answer

The goal of this code is to alphabetize and uppercase the inputted tuple of values. However, it is returning none when I run it. I find this odd since I have a return and I beilieve everything is in correct order. If you can help find the answer, thanks. Here is the code:
def sorter(*args):
args = " ".join(args)
uppercased = args.upper()
listed = list(uppercased)
sorted1 = listed.sort()
return sorted1
print(sorter('happy', 'apple', 'zain', 'freindly', 'jakob'))
Run your code in the Python Tutor Visualizer and step through it line by line, and you will see that listed.sort() doesn't return anything but instead mutates listed:
Before executing listed.sort():
After executing listed.sort():
The docs for list.sort also tell you that the list is sorted in-place, and the function signature doesn't have a return value.
The solution is therefore to use listed after sorting it, instead of creating a new variable sorted1.
(Note that there are other logical mistakes in your code which will prevent it from delivering the result you probably expected, even after this specific issue is fixed, but that's beyond the scope of this question and answer.)

I have a field <Age (D.O.B)>.I want the result to be i,e Age in brackets (unable to see my tag here)
I am using groovy.Please help.
I tried escaping the characters but unable to.
def msgBodyModified21 = msgBodyOriginal.replaceAll('<Age'+\\s+'(D.O.B)>', '<Age>')
Your quoting on the regexp is wrong. Use:
"<Age (D.O.B)>".replaceAll(/<Age\s+\(D\.O\.B\)>/, "<Age>")

I am doing an exercise in the Eloquent Javascript book and am having trouble getting access to a variable with JSON information in an adjacent .js file.
My file structure looks like this: eloquentJs (folder)> ancestry.js, chapter5json.js
I am including a require statement at the top of my chapter5json.js file:
require("./ancestry.js");
as well as:
module.exports = ANCESTRY_FILE;
at the bottom of my ancestry.js file.
When I try to run the following code in chapter5json.js:
var ancestry = JSON.parse(ANCESTRY_FILE);
console.log(ancestry.length);
I get an error that the
variable ANCESTRY_FILE is not defined.
Does anyone see what I'm doing wrong here?
You need to store the require statement like this: let ancestor = require("./ancestry.js")
Since the file is simply a json, simply use the ancestor like this:
let ancestry = JSON.parse(ancestor);
Now you can use all the variables using the reference of ancestry

I am using Excel 2013 and I put the following code into Sheet5 Code box and i try to compile it and get a Compile Error: Invalid Error Procedure
Worksheets("Sheet5").Range("C3").Value = Worksheets("Sheets1").Range("G3")
Are you sure your sheets are spelled properly ? One is named "Sheet5" and the other "Sheets1". Notice that one has an extra "s". Also I'd say that you should be consistent. If you use an explicit call to the "Value" property then do it on both sides. Note that you can omit it on both sides.
I'm guessing that you pasted the line of code into the worksheet module by itself and that the compile error you get is actually "Invalid Outside Procedure." If so, you need to put the code into a function or subroutine, something like:
Sub Test
Worksheets("Sheet5").Range("C3").Value = Worksheets("Sheets1").Range("G3")
End Sub
Then you'll get a "Subscript Out of Range" error because you don't have sheets with those names, which will be progress :).
