What Is ‘Gas Limit’ and How Does It Prevent Infinite Loops in Smart Contracts?

The gas limit is the maximum amount of gas a user is willing to spend on a particular transaction or smart contract execution. Every operation in a smart contract costs a certain amount of gas.

By setting a limit, the network ensures that if a contract enters an infinite loop, the execution will eventually run out of gas and halt, preventing the network from being clogged by computationally expensive, non-terminating code.
