DevExtreme React - Query Methods
aggregate(seed, step, finalize)
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
aggregate(step)
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
This is a shortcut for the aggregate(seed, step, finalize) method. It omits the seed and finalize parameters: instead of the seed value, the accumulator value is initialized with the first item's value; the finalize parameter's omission means that the calculation result is the accumulator value after the last step function's execution.
avg()
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
First, call the select(getter) method to select the object field that provides numeric values if the Query is associated with an array of objects, or use the avg(getter) method instead of avg().
avg(getter)
Calculates the average of all values found using a getter.
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
If the Query is associated with a numeric array, use the avg() method instead.
count()
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
enumerate()
Executes the Query. This is an asynchronous alternative to the toArray() method.
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
max()
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
First, call the select(getter) method to select the object field that provides numeric values if the Query is associated with an array of objects, or use the max(getter) method instead of max().
max(getter)
Calculates the maximum of all values found using a getter.
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
If the Query is associated with a numeric array, use the max() method instead.
min()
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
First, call the select(getter) method to select the object field that provides numeric values if the Query is associated with an array of objects, or use the min(getter) method instead of min().
min(getter)
Calculates the minumum of all values found using a getter.
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
If the Query is associated with a numeric array, use the min() method instead.
sortBy(getter)
Sorts data items by the specified getter in ascending order.
To sort data items by one more getter, call the thenBy(getter) or thenBy(getter, desc) method after sortBy.
See Also
sortBy(getter, desc)
Sorts data items by the specified getter in the specified sorting order.
Call the thenBy(getter) or thenBy(getter, desc) method after sortBy to sort data items by one more getter.

sum()
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
First, call the select(getter) method to select the object field that provides numeric values if the Query is associated with an array of objects, or use the sum(getter) method instead of sum().
sum(getter)
Calculates the sum of all values found using a getter.
A Promise that is resolved after the operation is completed. It is a native Promise or a jQuery.Promise when you use jQuery.
If the Query is associated with a numeric array, use the sum() method instead.
thenBy(getter)
Sorts data items by one more getter in ascending order.
This method can only follow the sortBy(getter), sortBy(getter, desc), thenBy(getter, desc), or another thenBy(getter) method call.
See Also
thenBy(getter, desc)
Sorts data items by one more getter in the specified sorting order.
This method can only follow the sortBy(getter), sortBy(getter, desc), thenBy(getter), or another thenBy(getter, desc) method call.

toArray()
Gets data items associated with the Query. This is a synchronous alternative to the enumerate() method.
