camelCase vs PascalCase

camelCase and PascalCase have many things in common. Both of them are used in a variety of places where words are concatenated, especially in programming languages where the use of spaces is not allowed when declaring variables and functions. The only significant difference between the two is the first character of the string. In camelCase, the first character is not capitalized and in PascalCase, the first letter, like all the others, is capitalized. Except for the differences in the first letter, both camelCase and PascalCase capitalize every first letter of a word.
