How to sort an array of objects by the value of a field using JavaScript? [duplicate]

Question

This question already has an answer here:

Given the following:

var array = [{"name":"zoe", "hotdogs":5},{"name":"april", "hotdogs":5},{"name":"ryan", "hot dogs":8}]

How can I sort the elements of the array by name using JavaScript?

var array = [{"name":"april", "hotdogs":5},{"name":"ryan", "hotdogs":8},{"name":"zoe", "hotdogs":5}]

Is there a way to apply some function to sort the objects? Are there helper libraries that help with performance?

I tried the following:

array.sort(function(a, b) {
    return a.name > b.name
});

But it appeared to have no effect on the resulting array when I try to print it out whatsoever.

Try return (a.name>b.name)-(b.name>a.name). .sort interprets 0 (AKA +false) as "equals" — Jan Dvorak, Mar 3 '13 at 17:30

Use .localeCompare().

array.sort(function(a, b) {
    return a.name.localeCompare(b.name)
});

The function should return integer, like C strcmp, so do:

if a.name > b.name {
  return 1;
} else if ( a.name == b.name) {
  return 0;
}
return -1
