Use of logical operators to reduce if else statements Javascript

function run_func(number) {
    // set number to 35 if it is not already set
    number = number || 35;
    console.log("Number is : " + number);
}

const check_this_var = 20;
check_this_var === 20 && run_func();
// SAME AS - if (check_this_var === 20) { run_func(); }
// Output: 10

check_this_var === 5 || run_func();
// SAME AS if (check_this_var != 5) { run_func(); }
// Output: 10
