About node.js : if-statement-error-while-running-source-bashrc-error

I tried running source ~/.bashrc but it shows

~/.bashrc (line 5): Missing end to balance this if statement
if  [ -x /usr/bin/starship ]; then
^
from sourcing file ~/.bashrc
source: Error while reading file “/home/alokjha/.bashrc”

How do i solve it?

I am currently on Garuda Linux (arch linux distro) and new in this linux universe, I want to install nvm, i followed steps as written in https://github.com/nvm-sh/nvm. I am not familiar with bash language so kindly help please ( Restart PC or Terminal is’t helping)

Edit: Complete BashRc file

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

# Load starship prompt if starship is installed
if  [ -x /usr/bin/starship ]; then
    __main() {
        local major="${BASH_VERSINFO[0]}"
        local minor="${BASH_VERSINFO[1]}"

        if ((major > 4)) || { ((major == 4)) && ((minor >= 1)); }; then
            source <("/usr/bin/starship" init bash --print-full-init)
        else
            source /dev/stdin <<<"$("/usr/bin/starship" init bash --print-full-init)"
        fi
    }
    __main
    unset -f __main
fi

I ran into the same problem.
First I want to make it clear that I am a newbie in Arch and Garuda, so maybe some of my statements are not entirely correct.

Just as someone told you in the comments, you are using fish, look at the title of the Konsole window. Or edit the .bashrc file and set the if to fish syntax (change fi to end) and you’ll see that the next error tells you clearly that you are using fish.

Quick “fix”

Switch to bash by running bash, then you can run source ~/.bashrc.

The problem with this is that if you exit bash (by executing exit) and return to fish, you lose what you get by executing source ~/.bashrc. I mean, you have to keep working in bash.

Solutions without switching to bash

Use nvm.fish.

Or convert the lines you need (the last 3 of your bashrc file) to fish syntax, and add them to the ~/.config/fish/config.fish file, then run source ~/.config/fish/config.fish.
