i have a problem with the code, idk how to optimalize the code to work for every new "person" in object.
customers_data={
'Ben10': [22, 30, 11, 17, 15, 52, 27, 12],
'Sameer': [5, 17, 30, 33, 40, 22, 26, 10, 11, 45],
'Zeeshan': [22, 30, 11, 5, 17, 30, 6, 57]
}
var count = 0
for (let e of customers_data.Ben10) { if (e >= 20) count ++}
if (count >= 5) {console.log("Ben10 has Premium Membership")}
count = 0
for (let e of customers_data.Sameer) { if (e >= 20) count ++}
if (count >= 5) {console.log("Sameer has Premium Membership")}
count = 0
for (let e of customers_data.Zeeshan) { if (e >= 20) count ++}
if (count >= 5) {console.log("Zeeshan has Premium Membership"); count = 0}
count = 0customers_data={
'Ben10': [22, 30, 11, 17, 15, 52, 27, 12],
'Sameer': [5, 17, 30, 33, 40, 22, 26, 10, 11, 45],
'Zeeshan': [22, 30, 11, 5, 17, 30, 6, 57]
}
var count = 0
for(let prop in customers_data)
{
for (let e of customers_data[prop]) { if (e >= 20) count ++}
if (count >= 5) {console.log(prop + " has Premium Membership")}
count = 0
}Use two loops. Outer to loop name => values, inner to loop values
let customers_data = {
'Ben10': [22, 30, 11, 17, 15, 52, 27, 12],
'Sameer': [5, 17, 30, 33, 40, 22, 26, 10, 11, 45],
'Zeeshan': [22, 30, 11, 5, 17, 30, 6, 57]
}
for (let dataKey in customers_data) {
let count = 0;
for (let value of customers_data[dataKey]) {
if (value >= 20) {
count++;
}
}
if (count >= 5) {
console.log(dataKey + " has Premium Membership");
}
}You can DRY this out a little by using a function into which you pass the data, and the name you want to check, and then return a message based on the result.
const customers_data = {
Ben10: [22, 30, 11, 17, 15, 52, 27, 12],
Sameer: [5, 17, 30, 33, 40, 22, 26, 10, 11, 45],
Zeeshan: [22, 30, 11, 5, 17, 30, 6, 57]
}
// Accept data and a name
function hasMembership(data, name) {
// `filter` out the numbers that are greater
// or equal to 20
const greaterThan20 = data[name].filter(entry => {
return entry >= 20;
});
// If the length of the filtered array is
// greater or equal to five, return a positive message
if (greaterThan20.length >= 5) {
return `${name} has Premium Membership!`;
}
// Otherwise return something else
return `Boo. No membership for ${name}.`;
}
console.log(hasMembership(customers_data, 'Ben10'));
console.log(hasMembership(customers_data, 'Sameer'));
console.log(hasMembership(customers_data, 'Zeeshan'));Additional documentation
