Variables Naming Convention

Variables naming convention:

Variables in JavaScript are case-sensitive. Case-sensitive means variables are treated differently depending on whether it is in capitals or lower-case text.


              12345
            
let name="Bob William";
console.log(name);

let NAME ="Jacob Thomas";
console.log(NAME);

We will get two different outputs because the name and NAME are two different variables.

Suppose there are 50 students in a class and you want to store this in a variable, and for that you need a variable name to store this information. Your task is to choose the suitable identifier for your variable name from these numberOfStudents, student, and std and print the value on the console.
