What are the constraints when using the + operator for merging strings, such as special characters or HTML tags?
There is a snippet of code (from a basic functioning website).
I have the code for a specific page - www.example.com
By solely modifying the URL (in the browser itself) I must navigate through various loops based on the provided code.
I am unable to alter the code itself.
My goal is to reach answer
The current result is closed.
Therefore, my question revolves around potential errors that could arise in the try block:
<some code>
if (req.query.L.length>999){
try {
const a = "<" + req.query.L + ">"
res.end(Closed.)
} catch{
res.end(answer)
}
}
else{
...
}
<some code>
I initiated with www.example.com
My current browser query appears like this www.example.com/?L[length]=1000
How can I achieve my objective?
Is my focus correct, specifically on string concatenation, or should I consider limitations of req.query? Any useful resources would be appreciated. This relates to an ExpressJS codebase.
