It returns the first input argument it is called with.
// Example
const input = [1, 2, 3]
const toObject = ({items, key: kfn = self, value: vfn = self}) =>
items.reduce((c /** container */, v) => (c[kfn(v)] = vfn(v), c), {})
toObject({items: input})
// Output {1:1, 2:2, 3:3}
toObject({items: input, value: Math.square})
// Output {1:1, 2:4, 3:6}constant
It is useful in the situations which require a function to return a fixed value.
// Example
const input = 'suhm'
const cfn = constant(input)
cfn()
// Output 'suhm'
