❌"Not enough Ether provided"

👇Error Handling in #Solidity Image
Some of the runtime errors are:
→out-of-gas error
→data type overflow error
→divide by zero error
→array-out-of-index error
→etc
After version 4.10 new error handling statements were introduced such as assert, require, revert.
This replaced Throw.
