3,001 PointsAssigning Object to Array elements
What is wrong with the following Code
var students = [];
var studentRec= {};
var names = ['name1','name2','name3','name4','name5'];
var tracks = ['Frontend Development','iOS','Web Design','Core Java','Groovy Grails'];
// Populate students array
for ( var i=0 ; i<=4 ; i+=1) {
studentRec.name = names[i];
studentRec.track = tracks[i];
studentRec.achievements = i;
studentRec.points = i;
students[i] = Object.create(studentRec);
}
// Display students array
for ( var i =0; i < students.length; i+=1) {
document.write ('{');
for ( var key in students[i]) {
document.write (key , ':', students[i][key] , ',');
}
document.write ('} <br>');
}
The output is :
Students
{name:name5,track:Groovy Grails,achievements:4,points:4,}
{name:name5,track:Groovy Grails,achievements:4,points:4,}
{name:name5,track:Groovy Grails,achievements:4,points:4,}
{name:name5,track:Groovy Grails,achievements:4,points:4,}
{name:name5,track:Groovy Grails,achievements:4,points:4,}

11,315 PointsIt's because every time your first "for" loop runs, all it's doing is reassigning the last value for i to all of those keys, until it ends on 4. Try deleting your second "for" loop & including the code you use to print out the values in that loop in your first loop. Hope that helps.
