string ops

given this string:

let x = 'cat.dog.dolphin.shark'

firstItemOf

j_.firstItemOf(x) // => 'cat'

lastItemOf

j_.lastItemOf(x) // => 'shark'

nthItemOf

j_.nthItemOf(x, 3) // => 'dolphin'

allButFirstItemOf

j_.allButFirstItemOf(x) // => 'dog.dolphin.shark'

allButLastItemOf

j_.allButLastItemOf(x) // => 'cat.dog.dolphin'

randomItemOf

j_.randomItemOf(x) // => 'dog' or maybe something else!

All above ops will auto-detect ',' '.' '/' & '|' in that order. For a different delimiter, pass it as the last argument:

let x = 'cat#dog#dolphin#shark'

j_.nthItemOf(x, 2, '#') // => 'dolphin'

array ops

j_ array ops only operate on flat object keys in an array.

Given this array:

let xmen = [{
  name: 'Nightcrawler',
  power: 'Teleportation'
}, {
  name: 'Cyclops',
  power: 'Optic blast'
}, {
  name: 'Rogue',
  power: 'Absorbing powers'
}, {
  name: 'Wolverine',
  power: 'Regeneration'
}]

indexFromArray

Searches an array of objects for a whole value for a specified key and returns the index of the first matching element

j_.indexFromArray(xmen, 'power', 'Optic blast') // => 1

queryArrayFirstMatch

Searches an array of objects for a whole value for a specified key and returns the first matching array element

j_.queryArrayFirstMatch(xmen, 'power', 'Optic blast') // => { "name": "Cyclops", "power": "Optic blast" }

queryArrayAllMatches

Searches an array of objects for a whole or partial value for a specified key and returns all matching array elements

j_.queryArrayAllMatches(xmen, 'power', 'po') // => [ { "name": "Nightcrawler", "power": "Teleportation" }, { "name": "Rogue", "power": "Absorbing powers" } ]

sortArrayBy

Sorts an array of objects by a key

uniqueKeysFromArray

Returns an array of unique keys from an array of objects
