Could anyone point out the issue with this JavaScript code?

Wanted to challenge your coding skills with this one! Can you identify the issue in the code below?

function run(){
 for(var i=0;i<arguments.length;i++){
  var type=arguments[i].split(" ")[0];
   if(type=="(write)"){
    var arr=arguments[i].split(" ");
    var str=[];
    for(var i=1;i<arr.length;i++){
     str.push(arr[i]);
    }
    var fin="\n"+str.join(" ");
    document.getElementById("console").textContent+=fin;
   }
  }
 }
run(
 "(write) I wonder if this works.",
 "(write) I think it DOES!"
);

Currently, only "I wonder if this works." is being displayed in the div and not "I think it DOES!". What's causing this issue? Could you provide the corrected version of the script?

Make sure to avoid reusing the same variable in a for loop. JavaScript has both functional scope and block scope, so it's important to use different variables for each iteration.

for(var k=1;k<arr.length;k++){
     str.push(arr[k]);
    }

Modify the loop by changing the variable i:

for (var i = 1; i < arr.length; i++){
    str.push(arr[i]);
}

You can replace i with a different variable or use let in ES6 to define i.

function start() {

  for (let x = 0; x < arguments.length; x++) {

    let item=arguments[x].split(" ")[0];

    if (item=="(print)") {
      let array=arguments[x].split(" ");
      let text=[];

      // Adjusted the loop to ensure proper execution
      for(let y = 1; y < array.length; y++) {
          text.push(array[y]);
      }

      let result="\n"+text.join(" ");
      console.log(result);
      document.getElementById("console").textContent+=result;
