Hello I am new to the JavaScript language.
I have a table1.data property that’s an array of objects with data about a school like:
{ schoolName: "School 1", telephone: "123456", address: "1st street, 1st road" }
Can I perhaps get an array of the telephone values from all the objects using JS? Please help.
>Solution :
All you need to do it traverse the items in the data, while grabbing the telephone field value.
Here is the long-way:
const table1 = {
data: [
{ schoolName: "School 1", telephone: "(111) 111-1111", address: "1st street" },
{ schoolName: "School 2", telephone: "(222) 222-2222", address: "2nd street" },
{ schoolName: "School 3", telephone: "(333) 333-3333", address: "3rd street" }
]
};
const phoneNumbers = [];
for (let i = 0; i < table1.data.length; i++) {
phoneNumbers.push(table1.data[i].telephone);
}
console.log(phoneNumbers);.as-console-wrapper { top: 0; max-height: 100% !important; }Here is the short way:
const table1 = {
data: [
{ schoolName: "School 1", telephone: "(111) 111-1111", address: "1st street" },
{ schoolName: "School 2", telephone: "(222) 222-2222", address: "2nd street" },
{ schoolName: "School 3", telephone: "(333) 333-3333", address: "3rd street" }
]
};
const phoneNumbers = table1.data.map(({ telephone }) => telephone);
console.log(phoneNumbers);.as-console-wrapper { top: 0; max-height: 100% !important; }
