# Given a number from 0 to 999,999,999,999, spell out that number in English.
2+
3+
## Instructions
4+
5+
- Given a number from 0 to 999,999,999,999, spell out that number in English.
6+
7+
### Step 1
8+
- Handle the basic case of 0 through 99.
9+
- If the input to the program is 22, then the output should be 'twenty-two'.
10+
- Your program should complain loudly if given a number outside the blessed range.
11+
- Some good test cases for this program are:\
12+
0\
13+
14\
14+
50\
15+
98\
16+
-1\
17+
100
18+
19+
### Step 2
20+
- Implement breaking a number up into chunks of thousands.
21+
- So 1234567890 should yield a list like 1, 234, 567, and 890, while the far simpler 1000 should yield just 1 and 0.
22+
- The program must also report any values that are out of range.
23+
24+
### Step 3
25+
- Now handle inserting the appropriate scale word between those chunks.
26+
- So 1234567890 should yield '1 billion 234 million 567 thousand 890'
27+
- The program must also report any values that are out of range. It's fine to stop at "trillion".
28+
29+
### Step 4
30+
- Put it all together to get nothing but plain English.
31+
- 12345 should give twelve thousand three hundred forty-five.
32+
- The program must also report any values that are out of range.
33+
34+
## Challenges (0/2 done)
35+
- [ ] 14 becomes "fourteen".
36+
- [ ] 1323 becomes "one thousand three hundred and twenty-three".
37+
38+
```js
39+
const sayNumberInEnglish = (n /* ADD MORE PARAMETERS IF NEEDED */) => {
40+
// Write your solution here
41+
return
42+
}
43+
44+
console.log(`5635 in english is: ${sayNumberInEnglish(5635)}`)

# Convert given seconds to space age on all planets of our solar system
2+
3+
## Instructions
4+
5+
**Given an age in seconds, calculate how old someone would be on:**
6+
7+
- Mercury: orbital period 0.2408467 Earth years
8+
- Venus: orbital period 0.61519726 Earth years
9+
- Earth: orbital period 1.0 Earth years, 365.25 Earth days, or 31557600 seconds
10+
- Mars: orbital period 1.8808158 Earth years
11+
- Jupiter: orbital period 11.862615 Earth years
12+
- Saturn: orbital period 29.447498 Earth years
13+
- Uranus: orbital period 84.016846 Earth years
14+
- Neptune: orbital period 164.79132 Earth years
15+
16+
**Pluto is not a planet**

So if your function was called with 436575687 as the argument i.e spaceAge(436575687) it should return { "Mercury": 57.44, "Venus": 22.49, "Earth": 13.83, "Mars": 7.36, "Jupiter": 1.17, "Saturn": 0.47, "Uranus": 0.16, "Neptune": 0.08 }
19+
20+
**IMPORTANT!!**
21+
22+
- Your spaceAge function should return the (already given) yearsInAllPlanets object after setting age on each planet (each property of the object)
23+
24+
- THE VALUE OF EACH PROPERTY SHOULD BE A NUMBER AND SHOULD HAVE MAXIMUM 2 DIGITS AFTER THE POINT example 4.34
25+

28+
- [ ] spaceAge(65965561) should return { 'Mercury': 8.68 'Venus': 3.4 'Earth': 2.09 'Mars': 1.11 'Jupiter': 0.18 'Saturn': 0.07 'Uranus': 0.02 'Neptune': 0.01 }
