append

Implement append in Scheme, TypeScript, Python, and Kotlin

Here is an implementation of the append function in Scheme:

(define (append lst1 lst2)
  (if (null? lst1)
#!/bin/sh
# 1. Define a base set of credentials with APPID and APPSECRET
. ~/.facebookrc
# APPID=
# APPSECRET=
function init {
echo
echo
// Resolve a dependency graph to sequence
// https://web.stanford.edu/~jurafsky/slp3/15.pdf
const resolve = (sentence, deps) => {
let ops = [];
while (sentence.length > 0) {
let word = sentence.pop();
if (deps.hasOwnProperty(word)) {
console.log('Dependencies exist for', word);
