An ng1-style injectable
This could be a (non-minified) function such as:
function injectableFunction(SomeDependency) {
}
or an explicitly annotated function (minify safe)
injectableFunction.$inject = [ 'SomeDependency' ];
function injectableFunction(SomeDependency) {
}
or an array style annotated function (minify safe)
['SomeDependency', function injectableFunction(SomeDependency) {
}];
Given a .map function, builds a .map function which throws an error if any mapped elements do not pass a truthyness test.
Given a .filter Predicate, builds a .filter Predicate which throws an error if any elements do not pass.
Given an array, returns true if the object is found in the array, (using indexOf)
Given an object, returns a new object, where each property is transformed by the callback function
pushes a values to an array and returns the value
Given an array, and an item, if the item is found in the array, it removes it (in-place). The same array is returned

Reduce function that returns true if all of the values are truthy.
Reduce function that returns true if all of the values are truthy.
Finds the common ancestor path between two states.
Finds the common ancestor path between two states.
The first state.
The second state.
Returns an array of state names in descending order, not including the root.
Reduce function that returns true if any of the values are truthy.
Reduce function that returns true if any of the values are truthy.
let vals = [ 0, null, undefined ]; vals.reduce(anyTrueR, true); // false
vals.push("hello world"); vals.reduce(anyTrueR, true); // true ```
Reduce function which builds an object from an array of [key, value] pairs.
Reduce function which builds an object from an array of [key, value] pairs.
Each iteration sets the key/val pair on the memo object, then returns the memo for the next iteration.
Each keyValueTuple should be an array with values [ key: string, value: any ]
var pairs = [ ["fookey", "fooval"], ["barkey", "barval"] ]
var pairsToObj = pairs.reduce((memo, pair) => applyPairs(memo, pair), {})
// pairsToObj == { fookey: "fooval", barkey: "barval" }
// Or, more simply:
var pairsToObj = pairs.reduce(applyPairs, {})
// pairsToObj == { fookey: "fooval", barkey: "barval" }
Given two or more parallel arrays, returns an array of tuples where each tuple is composed of [ a[i], b[i], ... z[i] ]
Given two or more parallel arrays, returns an array of tuples where each tuple is composed of [ a[i], b[i], ... z[i] ]
let foo = [ 0, 2, 4, 6 ];
let bar = [ 1, 3, 5, 7 ];
let baz = [ 10, 30, 50, 70 ];
arrayTuples(foo, bar); // [ [0, 1], [2, 3], [4, 5], [6, 7] ]
arrayTuples(foo, bar, baz); // [ [0, 1, 10], [2, 3, 30], [4, 5, 50], [6, 7, 70] ]
shallow copy from src to dest
Builds proxy functions on the to object which pass through to the from object.
Builds proxy functions on the to object which pass through to the from object.
For each key in fnNames, creates a proxy function on the to object.
The proxy function calls the real function on the from object.
This example creates an new class instance whose functions are prebound to the new'd object.
class Foo {
constructor(data) {
// Binds all functions from Foo.prototype to 'this',
// then copies them to 'this'
bindFunctions(Foo.prototype, this, this);
this.data = data;
}
log() {
console.log(this.data);
}
}
let myFoo = new Foo([1,2,3]);
var logit = myFoo.log;
logit(); // logs [1, 2, 3] from the myFoo 'this' instance
This example creates a bound version of a service function, and copies it to another object
var SomeService = {
this.data = [3, 4, 5];
this.log = function() {
console.log(this.data);
}
}
// Constructor fn
function OtherThing() {
// Binds all functions from SomeService to SomeService,
// then copies them to 'this'
bindFunctions(SomeService, this, SomeService);
}
let myOtherThing = new OtherThing();
myOtherThing.log(); // logs [3, 4, 5] from SomeService's 'this'
A function that returns the source object which contains the original functions to be bound
A function that returns the target object which will receive the bound functions
A function that returns the object which the functions will be bound to
The function names which will be bound (Defaults to all the functions found on the 'from' object)
If true, the binding of the function is delayed until the first time it's invoked
Applies a set of defaults to an options object. The options object is filtered to only those properties of the objects in the defaultsList. Earlier objects in the defaultsList take precedence when applying defaults.
