Step by Step solution about How to resolve the algorithm Find limit of recursion step by step in the JavaScript programming language
The provided JavaScript code defines a recursive function called recurse
that attempts to call itself repeatedly until an exception is thrown due to reaching the maximum call stack size. Here's a detailed explanation:
-
function recurse(depth)
: This function takes one argument,depth
, which is initially set to 1. -
Inside the
try
block, therecurse
function calls itself withdepth + 1
as the argument. This creates a recursive call stack where each function invocation increases thedepth
by 1. -
The
catch
block catches any exception that occurs during the recursive calls. In JavaScript, exceeding the maximum call stack size typically results in aRangeError
orMaximum call stack size exceeded
error. -
When the
catch
block is executed, it returns the current value ofdepth
. This represents the maximum recursion depth that the system can handle before reaching the maximum call stack size. -
In the main part of the code, the
maxRecursion
variable stores the result of invokingrecurse(1)
. -
Finally, the code uses
document.write
to display the maximum recursion depth achieved on the system.
When you run this code, it will attempt to recursively call the recurse
function until it reaches the maximum call stack size. The exact maximum recursion depth will vary depending on the system and browser configuration. The displayed message will show the maximum depth that can be achieved before the error occurs.
Source code in the javascript programming language
function recurse(depth)
{
try
{
return recurse(depth + 1);
}
catch(ex)
{
return depth;
}
}
var maxRecursion = recurse(1);
document.write("Recursion depth on this system is " + maxRecursion);
