Immutability
Remember how we assign different values to a variable through out the program? How we use setters in classes to modify the value of class variables? That is not allowed in FP. A variable once set remains unchanged. Sort of like, making all variables final.We usually think of variables as vessels that hold the values. The vessel can hold different values at different times. But in FP, variables are just another name for their values. Like, PI is always 3.14..Ever imagined a different value for PI? No? In the same way, every x, y in your program can now have a single value.
