I'm learning TypeScript and I have a situation where I am mapping an array of objects where each object can have different fields -- or to be specific, a field in the object is an object that can have different fields.

I'm not sure how to write an interface for this.

For instance, let's say I am trying to map my original data, which is Array to an array whose array elements will look like this:

First, I am duly embarrassed. I should know this.

I'm learning TypeScript and when I try to parse the data below (which I was given, told it was JSON) using JSON.parse() TypeScript complains that the data is not a string. I get that -- it isn't. If I wrap the entire thing in quotes, however, It doesn't work either.

I find myself lost and rather embarrassed as I'm a mid-level programmer. What am I missing here?

For what it's worth, I'm importing a large data array (the array is huge, I've only given the first two entries below) in my React app using

I am building a timer that has a pause and resume function. I found out the user can set multiple intervals when the timer is clicked more than once.

How can I prevent users from setting multiple intervals?

I tried inserting ($('.clock)).off("click") once the interval has set, but then couldn't figure out how to resume it. I thought I could do a statement pause = true, but not sure how I can use it in my code.
