function assert.equal
Usage in Deno
import assert from "node:assert";
equal(actual: unknown,expected: unknown,message?: string | Error,): void
Strict assertion mode
An alias of strictEqual.
Legacy assertion mode
Stability: 3 - Legacy: Use strictEqual instead.
Tests shallow, coercive equality between the actual and expected parameters
using the == operator. NaN is specially handled
and treated as being identical if both sides are NaN.
import assert from 'node:assert'; assert.equal(1, 1); // OK, 1 == 1 assert.equal(1, '1'); // OK, 1 == '1' assert.equal(NaN, NaN); // OK assert.equal(1, 2); // AssertionError: 1 == 2 assert.equal({ a: { b: 1 } }, { a: { b: 1 } }); // AssertionError: { a: { b: 1 } } == { a: { b: 1 } }
If the values are not equal, an AssertionError is thrown with a message property set equal to the value of the message parameter. If the message parameter is undefined, a default
error message is assigned. If the message parameter is an instance of an Error then it will be thrown instead of the AssertionError.
