May 16, 2017 · I have recently developed my own Object method to get an object property nested among objects and arrays regardless how deep it is. It utilizes a single line of recursive approach. Check this out. A computed property will only re-evaluate when some of its reactive dependencies have changed. This means as long as message has not changed, multiple access to the reversedMessage computed property will immediately return the previously computed result without having to run the function again.

This means as long as message has not changed, multiple access to the reversedMessage computed property will immediately return the previously computed result without having to run the function again. It does not use lodash. It's gotten complex enough that it probably should break into smaller pieces, and lodash might help with that. It includes not just gc , but also time from the original records, and will, in fact, include anything else from there.

Nested property support is on our roadmap for consideration in the future though the specifics of the API and support have not been worked out. jdalton closed this Nov 28, 2014 jdalton added the question label Nov 28, 2014 In JavaScript, you'll often find yourself passing functions that are used to iterate over arrays.

If you can write a recursive function in plain JS (or with combination of lodash) that will be the best one (by performance), but if you want skip recursion from your side and want to go for a simple readable code (which may not be best as per performance) then you can use lodash#cloneDeepWith for any purposes where you have to traverse a object recursively.

And I really don't want to include another library (case in point, MOUT) just for a single method. If you want to assign a variable to a nested object property that may or may not exist, _.get is the answer. But if what you want is a bool telling you whether or not a nested object property exists, you can use _.has.

Returns undefined if the path cannot be reached.
