I happen to be working with javascript and I have had to do this.

let ejemplo = "si";

if (ejemplo == "si") {
    //realiza 'x'
} else {
    //realiza 'y'
}

So far so good, if my variable ejemplo has the value "if" only performs 'x' and if it has a different value of "if" performs 'and'.

But when I make this change it does not happen the same

let ejemplo = "si";

if (ejemplo != "si") {
    //realiza 'x'
} else {
    //realiza 'y'
}

Any value that I give to ejemplo only performs 'x', in theory if I give "yes", I should do 'and', but that does not happen.

Any ideas?

The problem could be in how the programming languages use the 'Strings', to buy strings we recommend methods of the same languages or third-party frameworks. In this case you could solve it using this

string_a.localeCompare(string_b);

The function will return

0: they are the same

-1: string_a < string_b

1: string_a > string_b

And your function would be:

let ejemplo = "si";

if (ejemplo.localeCompare("si") !== 0) {
    //realiza 'x'
} else {
    //realiza 'y'
}
