Beginning coder here taking a course in js. I'm stuck on a problem asking me to write a function that takes an array of different countries and returns arrays of countries that have specified commonalities (eg: return countries that end in 'land' or 'ia' as an array). Here's the code I have written:
const countries = ['Finland', 'Sweden', 'Denmark', 'Norway', 'Iceland', 'Ethiopia']
function categorizeCountries(keyword) {
for (country of countries) {
if (keyword = 'land') {
console.log([countries.filter((country) => country.endsWith('land'))])
} else if (keyword = 'en') {
console.log([countries.filter((country) => country.endsWith('ia'))])
} else if (keyword ='ia') {
console.log([countries.filter((country) => country.endsWith('en'))])
} else {
console.log('Country does not Exists')
}
}
}
console.log(categorizeCountries(['land']))
console.log(categorizeCountries(['en']))
console.log(categorizeCountries(['ia']))
The console only returns the arrays that meet the 'land' specification, and returns the same array 5 times for each search. I've tried multiple things and this is what's got me the closest, I just don't know what I'm missing. Any help is welcome.
you are doing a lot of things wrong, but nice try nonetheless.
categorizeCountries(['in']) is useless, try calling it with just a string categorizeCountries('in')const countries = ['Finland', 'Sweden', 'Denmark', 'Norway', 'Iceland', 'Ethiopia']
function categorizeCountries(keyword) {
if (keyword == 'land') {
console.log(countries.filter((country) => country.endsWith('land')))
} else if (keyword == 'en') {
console.log(countries.filter((country) => country.endsWith('ia')))
} else if (keyword =='ia') {
console.log(countries.filter((country) => country.endsWith('en')))
} else {
console.log('Country does not Exists')
}
}
categorizeCountries('land')
categorizeCountries('en')
categorizeCountries('ia')result should be:
['Finland', 'Iceland']
['Ethiopia']
['Sweden']
.filter is already looping through the array; same as a for-loop. Using the param keyword on .endsWith would suffice
function categorizeCountries(keyword) {
return countries.filter((country) => country.endsWith(keyword));
}
