Why

This originated as an attempt to have assertions that are less verbose because assert.notDeepStrictEqual and the likes are ugly.

Example

const assert = require('assert-op')

assert('==', 2, 2)
assert('!==', 3, 4, 'should be unequal')
assert('<', 1, 2)
assert('!', null, 'should be falsy')
assert('!{===}', [], 'str', 'should be notDeepStrictEqual')
assert('{==}', [2], 2, 'should be deepEqual')
assert('!==', 3, 4)
assert('{===}', new Set([1,2]), new Set([1,2]))
assert('{===}', new Map([[1,2]]), new Map([[1,2]]))

Features

• Javascript Comparison Operators (==, !==, ===, !===, <, <=, >, >=)
• Negation (!, !!)
• Other symbols for nested object
  • {==}: deepEqual
  • !{==}: notDeepEqual
  • {===}: strictDeepEqual
  • !{===}: notStrictDeepEqual
• throws and !throws for assert.throws
• Single function
• Support ES2015 Set and Map
• ES Module, Browser IIFE and Node CJS support
