What am I doing wrong? In Javascript I am using the logical operator or in:
Use the logical operator or in variables 'foo' and 'bar' and assign it the result to the variable disjunction.
But it's not working for me; The code I use is the following:
foo = true;
bar = false;
if (foo || bar) {
disjunction = foo;
} else {
disjunction = bar;
}You can save the whole if block as follows:
let disjunction = (foo || bar);
By the way, if it's an exercise to practice, I advise you to understand well what that operator does:
let foo = "hola";
let bar = "mundo"
console.log(foo || bar);
console.log(bar || foo);
console.log(!!(bar || foo));
console.log(0 || foo);
console.log(foo || 0); Enter the if for the variable foo and that's why the variable disjunction has value true
let foo = true,
bar = false,
disjunction = undefined;
if (foo || bar) {
disjunction = foo;
} else {
disjunction = bar;
}
console.log(disjunction);var disjunction=0;
var foo = true;
var bar = false;
Boolean(disjunction); //retorna false por que disjunction vale 0
if (foo==true || bar==false) {
disjunction = foo;
} else {
disjunction = bar;
}
alert(disjunction):
If(foo=='true' || bar=='false') {}
