set-comparision

Language

ECMAScript 6

Usage

Import

Normal

const compare = require('set-comparision') // Equivalent to `template(template.OBJECT_EQUAL)`, see below

Advanced

const template = require('set-comparision/x')
const compare = template(myEqualFunction)

Functions

• A and B are instances of a Set-like class

• a and b are elements of A and B above

compare(A, B)

Equivalent to compare.equal(A, B)

compare.equal(A, B)

Returns true if every elements of A are found in B and vice versa

compare.subset(A, B)

Returns true if A is a subset of B

compare.superset(A, B)

Returns true if A is a superset of B

compare.notFunc(A, B)

• with Func is either Equal, Subset or Superset

Returns negative boolean of compare.func(A, B), e.g. compare.notEqual(A, B) is !compare.equal(A, B)

compare.xCompareSet(myEqualFunction)

Create a new set of set-comparision functions based on myEqualFunction as element equality function

myEqualFunction takes 2 parameters, which are a and b, and returns a boolean which true for equal and false otherwise

Equivalent to template(myEqualFunction) with template = require('set-comparision/x')

compare.for(myEqualFunction)

Equivalent to compare.xCompareSet(myEqualFunction)

compare.STRICT_EQUAL(a, b)

compare.STRICT_EQUAL = (a, b) => a === b

compare.OBJECT_EQUAL(a, b)

compare.OBJECT_EQUAL = (a, b) => Object.is(a, b)
