### Can Buy Item
`if / else if / else` chooses a branch from boolean conditions. Comparisons such as `<`, `>=`, `===` and logical operators `&&`, `||`, `!` combine the exact rules that decide which output is valid.

Hints
+
['Translate every case from the statement into a boolean condition before writing branches.', 'Order the checks so a more specific case is not swallowed by a broader condition.']
ANSWER
Solution
+
const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [balance, price] = input.trim().split(/\s+/).filter(Boolean).map(Number);
if (balance >= price) {
console.log("YES");
} else {
console.log("NO");
}
