Increment by 1, return current¶
Atomically increments by one the current value and returns the updated (current) value of the counter. Multiple concurrent client requests are guaranteed to return unique updated value.
// *******************************************
// Backendless.Counters approach
// *******************************************
Backendless.Counters.incrementAndGet( counterName )
.then( function( result ) {

// *******************************************
// Backendless.Counters.of() approach

Argument | Description |
---|---|
counterName |
name of the counter to increment. |
Example¶
var successCallback = function( response ) {
console.log( "counter value is - " + response );
};
var failureCallback = function( fault ) {
console.log( "error - " + fault.message );
};
// ************************************************

// ************************************************

// Backendless.Counters.of() approach
// ************************************************
var myCounter = Backendless.Counters.of( "my counter" );
