We can use the .toUpperCase() method to make a string all caps, such as:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var response = "Hello World".toUpperCase(); // now becomes "HELLO WORLD"
|
||
|
|
```
|
||
|
|
|
||
|
|
All we need to do now is check what the value of the environment variable is, which you can do like:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
if (process.env.VAR_NAME === "allCaps") {
|
||
|
|
resonse = "Hello World".toUpperCase();
|
||
|
|
} else {
|
||
|
|
response = "Hello World";
|
||
|
|
}
|
||
|
|
});
|
||
|
|
```
|
||
|
