Conditionals

Traditional conditional statements are not supported by o1js:

// this will NOT work
if (foo) {
x.assertEquals(y);
}

Instead, use the o1js built-in Provable.if() method, which is a ternary operator:

const x = Provable.if(new Bool(foo), a, b); // behaves like `foo ? a : b`

Try it out

Add the o1js built-in Provable.if() method:

const x = Provable.if(new Bool(isTrue), a, b);

Log the result of the ternary operator, which should now be 1:

Provable.log("x is now:", x)

Now build and run the script in the terminal:

npm run build && node build/src/index.js

The result of the ternary operator should now be 1.

Set the Bool value of the variable isTrue to false:

const isTrue = Bool(false);

Now build and run the script in the terminal:

npm run build && node build/src/index.js

The result of the ternary operator should now be 2.
