First projects and taste in music: differences between the age groups

The HackerRank Developer Skills Report 2019 shows differences between the different age groups among the survey participants in some areas. The survey participants were divided into the age groups 0 to 21, 22 to 37, 38 to 53 and 54 to 72 years. One of the questions was the first programming project. As a highlight among the first programming projects that respondents had described, HackerRank emphasized the manipulation of a flash game with the goal of infinite ammo and life. In the age group 0-21, calculators (28.37%) and sites with basic functionality (22.72%) were the most common initial projects. These projects were also particularly prevalent in the age group of 22 to 37 years (27.06% and 20.48%, respectively). The age group from 38 to 53 years did not mention a category of common games or other specific projects (32.97% and 19.67%, respectively). Members of the 54-72 age group also often cited games or other specific projects (32.35% and 27.21% respectively) as their first programming projects.

The questionnaire on the HackerRank Developer Skills Report 2019 also asked what music they hear during programming. Dance / electronic music was most commonly named by members of the three younger age groups as their music choice during programming. Classical music is the second most popular music genre (17.73%) among the members of the age group 0-21, with hip-hop and rap third (14.17%). Classical music (18.82% and 23.19%, respectively) and Rock (16.03% and 20.26% respectively) came second in the two middle-aged groups.
