error: `Parsing error: Identifier directly after number`.

How do you `console.log` that object in that image ? please add minimal example — Always Helping, Sep 05 '20 at 01:14
Identifiers cant start with numbers. You will have to access the property by string key. `object['3h']`. — Brenden, Sep 05 '20 at 01:15

you need to use bracket notation

    const object = { "3h": 0.44 }
    console.log(object["3h"])

Identifiers in Javascript can’t start with a number (You can check the exact rules at the link provided.

When dealing with object properties, you can use string literals for defining properties that won’t follow this rule (Which might also happen when dealing with JSON objects)

In order to access this properties you need to use a property accessor

On your case:

day.rain[‘3h’]
