[Most.js] Create Streams From Single Values With Most.js

Most provides many means for creating streams, the simplest of which is the offunction. In this lesson, we demonstrate the use of of to lift a single value into a stream. We also show off the just alias of of, as well as, a common method for currying a function.

Use CDN:

most.of('anything')

console.log(stream) // { source: { value: 'anything' } }

Use require:

const { just , of} = most

const log =
  label => value => logger(label, value);

most.of('anything')
  .observe(log('string'))

just('anything')
  .observe(log('string'))

just(23)
  .observe(log('number'))

// Bonus Bits
// Lift all the things
just(true)
  .observe(log('boolean'))

just({ a: 1, b: 2 })
  .observe(log('object'))

just([ 1, 2, 3])
  .observe(log('array'))

just(x => x)
  .observe(log('function'))

just(undefined)
  .observe(log('undefined'))

/*
string:
'anything'
string:
'anything'
number:
23
boolean:
true
object:
{ a: 1, b: 2 }
array:
[ 1, 2, 3 ]
function:
Function
undefined:
undefined
