Ufupisho wa Ukaguzi wa Uwongo katika JavaScript

Hebu sasa tuchunguze thamani ya kutofautiana kwa uwongo. Hii inaweza kufanywa kama ifuatavyo:

javascriptlet test = true;

if (test === false) {
  console.log('+++');
} else {
  console.log('---');
}

Mtu anaweza pia kuandika msingi sawa na kukanusha:

javascriptlet test = true;

if (test !== true) {
  console.log('+++');
} else {
  console.log('---');
}

Msimbo uliowasilishwa unaweza kuandikwa upya katika umbo lililofupishwa kama ifuatavyo:

javascriptlet test = true;

if (!test) {
  console.log('+++');
} else {
  console.log('---');
}

javascriptlet test = true;

if (test == false) {
  console.log('+++');
} else {
  console.log('---');
}

javascriptlet test = true;

if (test != true) {
  console.log('+++');
} else {
  console.log('---');
}

javascriptlet test = true;

if (test != false) {
  console.log('+++');
} else {
  console.log('---');
}
