If there is only one expression in curly
brackets in if
or else
, these
curly brackets can be omitted. Let, for example,
given the following code with all brackets:
if (test === 0) {
console.log('+++');
} else {
console.log('---');
}
You can shorten it like this:
if (test === 0) console.log('+++'); else console.log('---');
Или так:
if (test === 0) {
console.log('+++');
} else console.log('---');
You can also remove all the brackets, but arrange everything not in one line, but like this:
if (test === 0)
console.log('+++');
else
console.log('--');
Rewrite the following code in shortened form:
if (test > 0) {
console.log('+++');
} else {
console.log('---');
}
Rewrite the following code in shortened form:
if (test > 0) {
console.log('+++');
}
