Do we only focus on the key concepts in the modules or both the whole video and the key concepts when learning web development?

My story of how I learned to code and got a job in 4 months.

let person={ firstName: "SeaAmber", lastName: "Silver", age: 22, isStudent: No, hobbies: ['learning', 'coloring', 'journaling', 'writing', 'nature', 'listening to music', 'talking to Jesus/God', 'arts and crafts'] };

let hour =24; if (hour>=7 && hour <=10) { console.log("Morning time"); } else if (hour>=10) { console.log("Afternoon "); } else if (hour<24 && hour>42) { console.log("Evening Military Time"); } I'm learning and practicing one thing at a time, and I was practicing the if else statements in JavaScript. Visual code had told me which answer it was, and it came out to be Afternoon. Can someone also give me feedback. Did I do this correcctly. Visual code is telling me I did this right, but can someone give me feedback?

console.log("Hello World!") let age =25 if(age<25) { console.log("You cant enter this site") } else if(age>=25) { console.log("You can enter this site") } else console.log("Atleast 13 years old, you need parental permission")
