In this video, we will learn about Immutable in solidity.
Immutable is a keyword used for state variables that are assigned once during contract construction (in the constructor or at declaration) and cannot be changed afterward. Unlike constants, immutable variables can hold values that are not known until deployment, such as constructor arguments or block data.
