w salam sir ans is ( in const we cant change the value after declare but in variable we can change the value after declare)

[UzmaKhan-yokg]

const and var are both used to define and initialize the variables. The difference is that var keyword initialize the variables that can be reassigned and const variable-values can't be reassigned.
