Attach to prototype

Attach functions as non enumerable properties to the prototype of any object.

Please not that Attach to prototype is currently under development and not yet suited for production

Example

Generic

1import { constructAttachToPrototype } from "@wemnyelezxnpm/delectus-repellendus-neque"
2
3const attachToArray = constructAttachToPrototype(Array.prototype/*, options*/)
4attachToArray("removeByValue", function(value) {
5  const index = this.indexOf(value)
6  if (index === -1) return
7  this.splice(index, 1)
8})
9
10const ar = ["a", "b", "c"]
11
12ar.removeByValue("b")
13
14console.log(ar) // ["a", "c"]
15

Getter / Setter

Attach

1attachToArray("last", {
2  get() {
3    return this[this.length-1]
4  }
5  set(to) {
6    return this[this.length-1] = to
7  }
8})
9
10
11let ar = [1, 2, 3]
12
13ar.last      // return 3
14ar.last = 0  // return 0
15
16console.log(ar) // [1, 2, 0]

Apply

Just a different syntax to access getter / setter. Use Attach / apply depending on your coding conventions.

1import { constructApplyToPrototype } from "@wemnyelezxnpm/delectus-repellendus-neque"
2
3const attachToArray = constructApplyToPrototype(Array.prototype/*, options*/)
4attachToArray("last", {
5  get() {
6    return this[this.length-1]
7  }
8  set(to) {
9    return this[this.length-1] = to
10  }
11})
12
13
14let ar = [1, 2, 3]
15
16ar.last()   // return 3
17ar.last(0)  // return 0
18
19console.log(ar) // [1, 2, 0]

The generic functionality is also available on apply
