# V7010\. The return value of the function is required to be utilized\.

The analyzer has detected a suspicious method call, the return value of which is ignored\. Calling some methods without using their return values is pointless\.

The example:

```cpp
/**
 * @param {string} input
 * @returns {string}
 */
function escape(input) {
  input.replaceAll(";", "\\;")
  input.replaceAll(",", "\\,")
  return input
}
```

In this case, the `replaceAll` method is called, but the call result is ignored\. The `replaceAll` method returns a new string without modifying the original one on which the method was called\. As a result, the string containing the necessary modification is not used\.

For the modifications to take effect, save the result:

```cpp
/**
 * @param {string} input
 * @returns {string}
 */
function escape(input) {
  input = input.replaceAll(";", "\\;")
  input = input.replaceAll(",", "\\,")
  return input
}
```
