Rewrite the "switch" into an "if"
importance: 5
Write the code using if..else which would correspond to the following switch:
switch (browser) {
case 'Edge':
alert( "You've got the Edge!" );
break;
case 'Chrome':
case 'Firefox':
case 'Safari':
case 'Opera':
alert( 'Okay we support these browsers too' );
break;
default:
alert( 'We hope that this page looks ok!' );
}To precisely match the functionality of switch, the if must use a strict comparison '==='.
For given strings though, a simple '==' works too.
if(browser == 'Edge') {
alert("You've got the Edge!");
} else if (browser == 'Chrome'
|| browser == 'Firefox'
|| browser == 'Safari'
|| browser == 'Opera') {
alert( 'Okay we support these browsers too' );
} else {
alert( 'We hope that this page looks ok!' );
}Please note: the construct browser == 'Chrome' || browser == 'Firefox' … is split into multiple lines for better readability.
But the switch construct is still cleaner and more descriptive.
