javascript is about to get a pipeline operator (Goddess willing). here's why that's such a great thing, especially when combined with partial application & higher-order functions.

first off, let's talk about what the pipeline operator actually is, and why you should be so excited by it.

const lower = str => str.toLowerCase()
const stripWhiteSpace = str => str.replace(/[\s]+/g, '_')

const normalizedString = stripWhiteSpace(lower('    HELLO, worLD'))
 // 'hello, world'

const someVar = 'foo'

// the bad way
switch(someVar) {
  case foo:
    const response = 'someVar is foo!'
    break
    
  case bar:
     const response = 'someVar is bar!' // errors, 'assigning to constant variable response'
