TASK 153

elderflowerlime

I have a problem with this task, the console shows the result right way, but the status still shows that its failed.

helper.js :

export const isKeyPresent = (obj, key) => {
  let objKey = Object.keys(obj);
    for (let i=0; i<objKey.length; i++){
      if (objKey[i] === key) {
        return true; 
      } else {
        return false;
      }
    };
  }

The function isKeyPresent should test if the object has certain key -- This one is still red

Since you've already turned the object into a string using the Object.keys() method, you can skip some code and just use the .includes() string method if you wanted:

export const isKeyPresent = (obj, key) => {
	if (Object.keys(obj).includes(key)) {
		return true;
	} else {
		return false;
	}
};

@elderflowerlime with this condition you're only staying in the loop for a single iteration.

      if (objKey[i] === key) {
        return true; 
      } else {
        return false;
      }

Fix it!

Is there a way to solve this without using .keys method? I don't believe we have learned about it in the lectures? Unless I have forgotten about it?

Hacktinium Sure, you can get access to the object property like obj[key] and check if it's defined.
