Looks like JavaScript

Actually there are languages outside of Solidity, lll (lisp like) is the most intriguing to me, and Serpent(python like), there is one more (which I am failing to recall).

But Solidity is the flagship language.

Serpent is outdated; Viper is an up-and-coming replacement.

They both have curly braces but...

Solidity: strong static typing, class-based, all numbers are integers.

Javascript: weak dynamic typing, prototype-based, all numbers are floats.
