The JavaScript code console.log(0 || 1) logs the result of the conditional expression 0 || 1 to the console, which evaluates to 1 because 1 is the first "truthy" value encountered. This is due to the || operator's behavior of returning the first truthy value it encounters.
console.log(0 || 1)/**
* Returns the first truthy value from a list of values.
*
* @param {...any} values - A variable number of values to check.
* @returns {any} The first truthy value.
*/
function getTruthyValue(...values) {
// This function uses the short-circuit behavior of || to find the first truthy value
// It's a more concise and efficient way to do this, but the commented-out version
// shows how the filter and indexing approach works.
// return values.filter(Boolean)[0];
// Instead, we can use the || idiom to simplify the code
return values.find(Boolean) || null;
}
console.log(getTruthyValue(0, 1));console.log(0 || 1)
0 || 1 to the console.0 || 1 is a conditional operator.|| operator returns the first "truthy" value it encounters.0 is a falsy value and 1 is a truthy value.1.
