+## Typescript Implementation
+```typescript
+function checkPrime(num: number): boolean{
+    if (num < 2) {
+        return false;
+    }
+    for (let i = 2; i < num; i++) {
+        if (num % i === 0) {
+            return false;
+        }
+    }
+    return true;
+```
+
+## Javascript Implementation
+```javescript
+function checkPrime(num) {
+    if (num < 2) {
+        return false;
+    }
+    for (let i = 2; num; i++) {
+        if (num % i === 0) {
+            return false;
+        }
+    }
+    return true;
+}
+```
+
+## Explanation
+Typescript implementation uses num that takes a single argument `number`. It returns true if the number is even (i.e., when the remainder of the division of the number by 2 is zero), otherwise, it returns `false`. Uses console.log to call functions and printing to console/output.
+
+Example Usage:
+
+console.log(checkPrime(2)); // true
+
+console.log(checkPrime(4)); // false
+
+Javascript implementation uses the same function `num` that takes a single argument `number`. It returns true using the same logic as typescript and `false` otherwise. ses console.log to call functions and printing to console/output.
+
+Example Usage:
+
+console.log(checkPrime(2)); // true
+
+console.log(checkPrime(4)); // false
+
+### Differences
+1. **Syntax**:
+While typescript requires annotations, javascript is a bit different because you don't need to use `:number` or `:boolean`
