js answer:
let incrementString = str => str.replace(/([0-8]|\d?9+)?$/, (e) => e ? + e + 1 : 1)
function incrementString (strng) {
return strng.replace(/(\d*)$/, (_, p1) => p1 ? String(+p1 + 1).padStart(p1.length, 0) : 1);
}
function incrementString (strng) {
var m = strng.match(/^(\w*?)(\d*)$/);
var next = (parseInt('0'+m[2], 10) + 1) + '';
return m[1] + m[2].slice(0, -next.length) + next;
}

write a function which increments a string, to create a new string.
If the string already ends with a number, the number should be incremented by 1.
If the string does not end with a number. the number 1 should be appended to the new string.
Examples:
foo -> foo1
foobar23 -> foobar24
foo0042 -> foo0043
foo9 -> foo10
foo099 -> foo100
Attention: If the number has leading zeros the amount of digits should be considered.

The rgb function is incomplete. Complete it so that passing in RGB decimal values will result in a hexadecimal representation being returned. Valid decimal values for RGB are 0 - 255. Any values that fall out of that range must be rounded to the closest valid value.
Note: Your answer should always be 6 characters long, the shorthand with 3 will not work here.
The following are examples of expected output values:
rgb(255, 255, 255) // returns FFFFFF
rgb(255, 255, 300) // returns FFFFFF
rgb(0,0,0) // returns 000000
rgb(148, 0, 211) // returns 9400D3
so the function accept 3 number 0-255 and will return hex values...

JS answer:
function capital(capitals){
return capitals.length > 0 ? capitals.map(cap =>
The capital of ${cap[Object.keys(cap)[0]]} is ${cap[Object.keys(cap)[1]]}) : "No Information Given..."
}
function capital(capitals) {
return capitals.map(function(e) {
return 'The capital of ' + (e.state || e.country) + ' is ' + e.capital
})
}
function capital(capitals){
return capitals.map(c => The capital of ${c.state||c.country} is ${c.capital});
}
function capital(capitals){
return capitals.map(function (hash) {
return Object.keys(hash).reduce(function (a, b) {
return 'The capital of ' + hash[a] + ' is ' + hash[b]
})
})

Write a method that takes a sequence of objects with two keys each: country or state, and capital. Keys may be symbols or strings
The method should return an array of sentences declaring the state or country and its capital.
{state: 'Maine', capital: 'Augusta'}
should return
"The capital of Maine is Augusta"
{'country' : 'Spain', 'capital' : 'Madrid'}
"The capital of Spain is Madrid"
[{"state" : 'Maine', capital: 'Augusta'}, {country: 'Spain', "capital" : "Madrid"}]
["The capital of Spain is Madrid", "The capital of Maine is Augusta"]
