What is Double Spending in Cryptocurrency?

I've just started diving into cryptocurrency and came across the term "double spending." Can someone explain what it means and why it's a concern?

This is a critical concern because it could undermine the integrity of the currency system. Cryptocurrencies like Bitcoin address this problem through the use of blockchain and consensus mechanisms among nodes.
