How do I convert .bash_profile to .zprofile

With OSX Catalina they want you to use zsh for the shell and I had a bash profile (that I “borrowed”) that I like. But I’m not a shell expert and I don’t know how to convert it. Below is the .bash_profile I would like to convert.

#!/bin/bash

export TERM=xterm-256color
export CLICOLOR=1
export LSCOLORS=Fafacxdxbxegedabagacad

GREEN=$(tput setaf 2);
YELLOW=$(tput setaf 3);
RESET=$(tput sgr0);

function get_branch {
 git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* (.*)/ (1)/'
}

function random_element {
 declare -a array=("$@")
 r=$((RANDOM % ${#array[@]}))
 printf "%sn" "${array[$r]}"
}

setEmoji () {
 EMOJI="$*"
 PS1="${YELLOW}w${GREEN}$(get_branch)${RESET} ${EMOJI}n$ ";
}

newRandomEmoji () {
  setEmoji "$(random_element 😅 👽 🔥 🚀 👻 ⛄ 👾 🍔 😄 🍰 🐑 😎 🏎 🤖 😇 😼 💪 🦄 🥓 🌮 🎉 💯 ⚛️ 🐠 🐳 🐿 🥳 🤩 🤯 🤠 👨‍💻 🦸‍ 🧝‍ 🧞‍ 🧙‍ 👨‍🚀 👨‍🔬 🕺 🦁 🐶 🐵 🐻 🦊 🐙 🦎 🦖 🦕 🦍 🦈 🐊 🦂 🐍 🐢 🐘 🐉 🦚 ✨ ☄️ ⚡️ 💥 💫 🧬 🔮 ⚗️ 🎊 🔭 ⚪️ 🔱)"
}

newRandomEmoji

alias jestify="PS1="🃏n$ "";
alias cypressify="PS1="🌀n$ "";

# history size
HISTSIZE=5000
HISTFILESIZE=10000

# PATH ALTERATIONS
## Node
PATH="/usr/local/bin:$PATH:./node_modules/.bin";

# Custom bins
PATH="$PATH:$HOME/.bin";

CDPATH=.:$HOME:$HOME/code:$HOME/Desktop

alias ll="ls -la"
alias cls="clear"

alias pj="cd ~/Projects"

Namely I can do without the random emoji (it was just fun). But I want the color prompt. I liked having the branch listed in the prompt so I always knew if I was in a git repo and what branch was currently checked out.

I appreciate any help.
