TIL about console.assert()

POSTED ON:

TAGS: javascript devtools

We've all been there. We did something like this.

if (value != 10) {
    console.log("value does not equal 10");
}

You can instead use console.assert() to show that message.

console.assert(value < 10, "value is greater than 10");

What does it do? Via MDN:

console.assert() - Log a message and stack trace to console if the first argument is false.

ONE THING TO NOTE: Encrypting a script is stronger than obfuscation, both methods are still not adequate to protect secret content. Honestly, I don't think it's worth it on a production site, and instead just go with pure server-side if you want security. But it's fascinating.
