+Consider the following code block. What is the correct Output?
+```javascript
+function frequencyCounter(arr1, arr2){
+if(arr1.length !== arr2.length){
+    return false;
+}
+for(let i = 0; i < arr1.length; i++){
+    let correctIndex = arr2.indexOf(arr1[i] ** 2)
+    if(correctIndex === -1) {
+    return false;
+    }
+    arr2.splice(correctIndex,1)
+}
+    return true;
+}
+console.log(frequencyCounter([1,2,3,2], [9,1,4,4]));  
+```
+<!-- explanation -->
+The function should return true if every value in the array has it's corresponding value squared in the second array.Also frequency of values must be the same.Below Block will give output as false.
+
+```javascript
+function frequencyCounter(arr1, arr2){
+if(arr1.length !== arr2.length){
+    return false;
+}
+for(let i = 0; i < arr1.length; i++){
+    let correctIndex = arr2.indexOf(arr1[i] ** 2)
+    if(correctIndex === -1) {
+    return false;
+    }
+    arr2.splice(correctIndex,1)
+}
+    return true;
+}
+console.log(frequencyCounter([1,2,3,2], [9,1]));   
+```
