QUESTION
Working with react leaflet and a water api. I create an array of objects from the data obtained from the API, console log shows I have all the correct data, particularly at line 109 it does output the correct information. Yet, on lines 254 and 255, using obj2[1]
just gives me 'TypeError: Cannot read property 'name' of undefined.' Switching the index at those two lines back to 0 makes it compiles and run, but that's obviously not the right data. What is going on here?
ANSWER
Answered 2021-May-30 at 22:48The problem is you make the API call and this process takes time to get data from the server so the first time the obj2 is empty so when you call obj2[1].name is throwing error

Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I'd like to know how to do 2 execution plans: "traditional" execution plan joins (A with B) and then C. The "new" plan joins (A with B) then (A with C) and then joins the result of those joins so there would be 3 joins. How would I code the traditional and new plan in Oracle SQLPlus given the code below? I also need to measure the time complexity of both methods to show that the new plan takes less time, which I believe I just do with set timer on; The joins can be on whatever attributes work. Same with select statements. I made a artist, b album, c track, and d played.
Here's the database:

Answered 2021-Apr-18 at 06:13Your question doesn't make a lot of sense, because it's imposing bizarre restrictions that we can't really assess, but I don't mind telling you how to join two joins

It's expecting the results to be "pm.expect(jsonData.name).to.eql('Three Rivers Campground')", Isn't that what is happening below? The server is returning a JSON object where it's .name is equal to 'Three Rivers Campground'.
