The Problem

The Python Code

Here, two essential pieces of information are merged into one string - the link and caption.

The JavaScript Code

Upon executing this JavaScript code, the output is not what was expected. You might observe that only part of the caption is logged, specifically, just "fsf".

Understanding the Issue

The confusion arises from how command line arguments are handled in programming:

Command line arguments are split by spaces.

The output from your command line shows the first word of the caption, implying that it's being treated as separate arguments.

Output Analysis

Your console output indicates the parameters received:

The commands are indexed, starting from zero:

The actual value of the caption is split into two arguments due to the presence of a space.

Solution: Passing Caption with Spaces

To ensure that the entire caption is treated as a single argument, we can modify how the caption is wrapped in the Python code. Here’s the updated approach:

Why This Works

Conclusion

Parameter passing between different programming languages can be intricate, especially when dealing with spaces in argument strings. To summarize:

Command line arguments are split by spaces.

Utilize quotes around strings with spaces to treat them as single arguments.
