It's worth noting that if you are creating a vector for this purpose, you may use the vector's constructor directly:

std::vector> vectorWordsList( mappedWordsList.begin(), mappedWordsList.end() );

In C++17, you may also omit the vector's template arguments to have the compiler deduce them:

std::vector vectorWordsList( mappedWordsList.begin(), mappedWordsList.end() );
