This function iterates over every element of the string and calls the closure to work on that element. This function will reduce the string to a single value, from the right to the left, and will return the value.
NOTE: This function is not available in Lucee 5.x or lower. Potentially use reverse() instead.
stringReduceRight(string, callback, initialValue)
returns any
string.reduceRight(callback, initialValue)
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
| string | string | Yes | The input string. | |
| callback | any | Yes | Closure or a function reference that will be called for each iteration. | |
| initialValue | any | Yes | Initial value which will be used for the reduce operation. |
| Name | Type | Required | Description | | — | — | — | — | | result | any | No | The result of the reduce operation after the previous iteration. | item | any | No | The value for the current iteration’s item. | index | numeric | No | The current index for the iteration | array | array | No | A reference of the original array
Demonstrate how the function works from right to left.
myString="abcd";
newString=stringReduceRight(myString,function(prev,next,idx,arr){ return prev & next & idx },"")
writedump(newString);
This function will be added to Lucee in Version 6. But if you need to reverse a string now, use the reverse() function.
myString="abcd";
newString=myString.reverse();
writedump(newString);
