+# 0005 isJavaScriptFile ( L-B )
+
+## Problem
+
+Write a function that returns an new array of true and false values based on the input array. The function should return true if the corresponding element is a JavaScript file.
+
+## Test Cases
+
+- isJavaScriptFile(['L-B.js', 'L-B.css', 'L-B.html', 'L-B.js']); // [true, false, false, true]
+- isJavaScriptFile(['L-B.js', 'L-B.js', 'L-B.js', 'L-B.js']); // [true, true, true, true]
+- isJavaScriptFile(['L-B.css', 'L-B.css', 'L-B.css', 'L-B.css']); // [false, false, false, false]
+ 
+## Solution
+
+```javascript
+function isJavaScript(file) {
+    let trueName = [];
+    for (const ele of file) {
+        if (ele.endsWith(".js")){
+            trueName.push(true)
+        }
+        else{
+            trueName.push(false)
+        }
+    }
+    return trueName;
+}
+
+const fileInputName = ["javascriptProject.js", "app.js","js.png","clock.java", "image.js"];
+const fileName = isJavaScript(fileInputName);
+```
+
+## How it works
+
+- The function takes an array as a parameter.
+- It creates a variable called trueName and assigns it a value of an empty array.
+- It creates a for loop that iterates through the array.
+- It checks if the element ends with ".js".
+- If it does, it pushes true to the trueName array.
+- If it doesn't, it pushes false to the trueName array.
+- It returns the value of trueName.
