switch
statement can be easier to write than many chained if
/else if
statements. The following:
if (val === 1) {can be replaced with:
answer = "a";
} else if (val === 2) {
answer = "b";
} else {
answer = "c";
}
switch(val) {
case 1:
answer = "a";
break;
case 2:
answer = "b";
break;
default:
answer = "c";
}
if
/else if
statements into a switch
statement.
