var plumb = require('plumb')
var reverseString = plumb(
plumb.invoke('split')
plumb.invoke('reverse')
plumb.invoke('join','')
)
// => Function
reverseString('hello')
// => "olleh"
Using jsig notation
plumb(...fns: Function) => (val: Value) => Value
Reutrns a function composing each of the argument functions in order. The return value of each function is used as the argument for each successive function.
plumb.pipe(val: Value, ...fns: Function) => Value
Immediately invoke a composition of functions fns
on the value val
. It helps me to think about fns
as a crazy pachinko machine and val
as the ball going in.
Equivalent to plumb(fns)(val)
plumb.invoke(methodName: String, ...args?: Value) => Function
Creates a function which invokes a method on an object, optionally with fixed arguments.
Example:
plumb.invoke('foo','bar')
returns the equivalent of
function callFoo(obj) {
return obj.foo('bar')
}
plumb.tap(fn: Function) => (Value) => Value
Create a function which passes a value through (identity) and calls a function fn
with that value.
Example:
var log = plumb.tap(function (x) { console.log(x)})
log(10)
// => 10
// side effect: console.log(10) was called
$ npm install plumb
From project root:
