Interpreter

javascript if you cannot read.

function ctw(p){
const s=[];
let c=0;
console.log("--- Cotwo Interpreter Output ---");
let k="";
while(c<p.length){
const r=p[c];
if(r==='['){
if(s.length>0){
const l=s[s.length-1];
const sl=s.length>1?s[s.length-2]:undefined;
if(l!=='"'){
if(l!='|'){
k+=l;
console.log(k);
}else {
if(s.length>=3){
s[s.length-1]=Number(s[s.length-3])+Number(sl);
}else {
console.error("Error: Stack too small for addition operation.");
}}} else {
if(l!=sl){
c++;
}}}
c++;
} else if(r===']'){
const currentLast=s.length>0?s[s.length-1]:undefined;
const secondLast=s.length>1?s[s.length-2]:undefined;
if(currentLast!=='"'){
if(currentLast==='|'){
s.pop();
s.splice(0,0,s.pop());
}else {
let u=prompt("Cotwo: Enter input:");
u=u[0];
s.push(u);
c++;
}} else {
if(currentLast===secondLast){
c=(Number(secondLast)*10)+Number(currentLast);
}else {
c++;
}}} else {
s.push(r);
c++;
}}
console.log("--- Program Finished ---");
