ArrayReduce()

Iterates over every entry of the given array and calls the closure with every element. This function will reduce the array to a single value and will return the value.


	ArrayReduce( array=array, closure=function, initialValue=object );

Returns: any

Argument Description

Argument	Description
array _{array, required}	array to iterate _{Alias: object}
closure _{function, required}	function/closure that implements the following constructor `function(any result, object value, [, numeric index [, array]]){ return result; }` _{Alias: function, callback, udf}
initialValue _{object, optional}	initial value passed as part of the first closure call _{Alias: initial, initalValue}

Examples

reduced = ArrayReduce( [1,2,3,4], function( carry, value ){
    return carry + value;
}, 0 );
dump( reduced ); // yields 10

    return carry & ' ' & value;
}, '' );
dump( reduced ); // yields 'hello there lucee'
