почему когда задаю имя свойства выдает ошибку?

var points = [ 
  "Aleks", 0, 
  "Irina", 60, 
  "Gleb", 30, 
  "Anton", 30, 
  "Victoria", 30, 
  "Valera", 100 
]; 
 
var students = []; 
for (var i = 0; i < points.length; i+=2){ 
 
  students.push({ [points[i]] : points[i+1] }); 
} 
console.log(students);

var points = [ 
  "Aleks", 0, 
  "Irina", 60, 
  "Gleb", 30, 
  "Anton", 30, 
  "Victoria", 30, 
  "Valera", 100 
]; 
 
 
var students = []; 
for (var i = 0; i < points.length - 1; i = i+2) { 
  var newObj = {}; 
  newObj[points[i]] = points[i + 1]; 
  students.push(newObj); 
} 
console.log(students);
