Sum of object values

[prashasti-k]

I have an object with over 20 keys and each of the values is a number. I want an expression to return the sum of those values. In javascript we would do something like
Object.values(c).reduce((sum, b) => sum + b, 0)
How can I modify this to an expression?

I don't see a way to currently get all the values of an object, or convert an object to something that can be mapped.

Luckily you can import a function:

math.import({ values: Object.values })

And then call your function.

math.evaluate("sum(values({ a: 1, b: 2 }))")  // yields 3

Or as one line.

math.evaluate('sum(values({a:1,b:2}))', { values: Object.values })
