RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including human-elapsed. Try it out:
const HumanToElapsed = require('human-elapsed')
const tests = [
[
'should return every unit in plural',
1000122,
'11 days 13 hours 48 minutes 42 seconds'
],
[
'should return every unit in singular',
90061,
'1 day 1 hour 1 minute 1 second'
],
[
'should return only 1 day',
86400,
'1 day'
],
[
'should return only 1 hour',
3600,
'1 hour'
],
[
'should return only 1 minute',
60,
'1 minute'
],
[
'should return only 1 second',
1,
'1 second'
],
[
'should return blank',
0,
''
]
]
const execution = tests
.map(([desc, test, expected]) => {
return {
desc,
pass: HumanToElapsed(test) === expected,
result: HumanToElapsed(test),
expected
}
})
.map(itm => {
const retval = `${'✔'} ${itm.desc}`
if (itm.pass) {
return [null, retval]
} else {
return [
[
itm.desc,
`expected: ${itm.expected}`,
`returned: ${itm.result}`
].join('\n - '),
null
]
}
})
execution
.filter(([fail]) => !fail)
.forEach(([,success]) => {
console.log(success)
})
const fail = execution.filter(([fail]) => fail)
fail.forEach(([fail]) => {
console.error(`${`✗`} ${fail}`)
})
