No 'arguments' object: Arrow functions do not have their own 'argume...
Identify and list duplicate characters in a given string efficiently.
Use a hash map to count occurrences of each character. Example: 'hello' -> {'h': 1, 'e': 1, 'l': 2, 'o': 1}

Overfitting is when a model learns the training data too well, leading to poor performance on new, unseen data.
Overfitting occurs when a model is too complex and captures noise in the training data.

Examples of overfitting include a decision tree with too many branches or a neural network with too many hidden layers.
