var scratchData = [
{name: 'Billy Boy', grade: 'D'},
{name: 'Serious Sara', grade: 'B'},
{name: 'Tepid Tom', grade: 'C'} ];
function makeStudentsReport(data)
How can i make this function return a string that say name + 'is getting an' + grade; I must return an object.
You could map the result strings with Array#map
function makeStudentsReport(data) {
return data.map(function (a) {
return a.name + ' is getting a' + ('AEF'.indexOf(a.grade) === -1 ? "" : "n" ) + ' ' + a.grade;
});
}
var scratchData = [{ name: 'Billy Boy', grade: 'D' }, { name: 'Serious Sara', grade: 'B' }, { name: 'Tepid Tom', grade: 'C' }, { name: 'Jet Jane', grade: 'A' }];
console.log(makeStudentsReport(scratchData));
..is getting a"+("AEF".indexOf(a.grade)==-1?"n":"") + a.grade
Well David, you can use the map function as well as Nina did, or you can just use the typical for loop way:
var scratchData = [
{name: 'Billy Boy', grade: 'D'},
{name: 'Serious Sara', grade: 'B'},
{name: 'Tepid Tom', grade: 'C'} ];
var get = ' is getting an '; // declaring it with var so it's easier to use
function makeStudentsReport(data) { // data will be the array
for (var i = 0; i < data.length; i++){
var everyObject = data[i]; // everyObject is every object in the array
console.log(everyObject.name + get + everyObject.grade);
}
}
makeStudentsReport(scratchData); // passing the array as a parameter to the function
Or more simple you can use Array.forEach() method:
function makeStudentsReport(data) {
data.forEach(function(object){
console.log(object.name + get + object.grade);
});
}
makeStudentsReport(scratchData);
for (var i=0;i<scratchData.length;i++) { console.log(scratchData[i].name+' is getting a(n) '+ scratchData[i].grade); }
