Module assert 

Node assert module. Failing assertions throw an AssertionError (returned as an Err, which the host surfaces as a thrown JS exception).

Constants

METHODS

Functions

assert_ok

assert(value[, message]) — throws unless value is truthy.

call

construct_assertion_error

new assert.AssertionError(options) — a real Error-prototype-linked object carrying name/message/code/actual/expected/operator. Parent wires this to construct("AssertionError") and constant("assert","AssertionError").

deep_equal

Structural equality. strict compares leaves with ===, otherwise ==.

strict_call

The strict-mode variants (assert.strict.equal === assert.strictEqual). Maps the loose method names onto their strict counterparts, then delegates.
