Array filter from a letter

[RitaSghe]

@Colin
no, msg.payload is my array that contains more value like title, title2, isCheked, icon
and I try to filter by value "title2" to include all elements that are alphabetically after "D", (including "D"), so D, E, F, G .....

JSON Array Filtering - Function Node

See this post from earlier today which asks an almost identical question. Filter Array of Objects [Edit] Note that if you are using the filter function you have to call filter on the Array, which is msg.payload.trains, not msg.payload.CA_MSG, and you have to check for equality (at least I assume that is what you want) so the test is el.area_id === "RT") [Edit] as pointed out below that should be el.CA_MSG.area_id

there is one your post for the filter I use (modified for my values of course)
