JavaScript assertions debugging - console.assert()

Writes an error message to the console if the assertion is false. Otherwise, if the assertion is true, this does nothing.
console.assert('one' === 1)

Multiple arguments can be provided after the assertion–these can be strings or other objects–that will only be printed if the assertion is false:

console.assert does not throw an AssertionError (except in Node.js), meaning that this method is incompatible with most testing frameworks and that code execution will not break on a failed assertion.
