npm install assert-polyfill --save
NodeJS v0 deepStrictEqual
/notDeepStrictEqual
is unavailable.
var assert = require('power-assert');
assert.deepStrictEqual(['foo'], ['foo'])
// TypeError: undefined is not a function
assert.notDeepStrictEqual(['foo'], ['bar'])
// TypeError: undefined is not a function
if above function is undefined
, assert-polyfill
defines the polyfill functions.
require('assert-polyfill');
var assert = require('power-assert');
assert.deepStrictEqual(['foo'], ['foo']) // pass
assert.notDeepStrictEqual(['foo'], ['bar']) // pass
even if --require
in mocha, it is similar.
