--description--
The Math object in JavaScript contains static properties and methods for mathematical constants and functions. One of those is Math.random(), which generates a random number from 0 (inclusive) to 1 (exclusive). Іншим є Math.floor(), яке заокруглює задане число до найближчого цілого числа.
З їх використанням ви можете згенерувати випадкове число в межах діапазону. Наприклад, це генерує випадкове число від 1 до 5: Math.floor(Math.random() * 5) + 1;.
Following this pattern, use the addition operator (+) to add a random number between 1 and the value of xp to your monsterHealth -= weapons[currentWeapon].power.
--hints--
Ви повинні використати той рядок monsterHealth, який ви вже писали.
assert.lengthOf(attack.toString().match(/monsterHealth/g), 1);
Ви повинні додати до значення weapons[currentWeapon].power.
assert.match(attack.toString(), /monsterHealth\s*-=\s*weapons\[currentWeapon\]\.power\s*\+/);
Ви повинні використати Math.floor().
assert.match(attack.toString(), /Math\.floor/);
Ви повинні використати Math.random().
assert.match(attack.toString(), /Math\.random/);
Ви повинні помножити Math.random() на значення xp.
assert.match(attack.toString(), /Math\.random\(\)\s*\*\s*xp/);
Ви повинні використати Math.floor(), щоб заокруглити результат Math.random() * xp.
assert.match(attack.toString(), /Math\.floor\(\s*Math\.random\(\)\s*\*\s*xp\s*.*\)/);
Ви повинні додати 1 до результату Math.floor().
assert.match(attack.toString(), /Math\.floor\(Math\.random\(\)\s*\*\s*xp(?:\s*\+\s*1)?\)(?:\s*\+ 1)?/);
Ви повинні додати результат Math.floor(Math.random() * xp) + 1 до результату weapons[currentWeapon].power.
assert.match(attack.toString(), /monsterHealth\s*-=\s*weapons\[currentWeapon\]\.power\s*\+\s*Math\.floor\(Math\.random\(\)\s*\*\s*xp(?:\s*\+\s*1)?\)(?:\s*\+ 1)?/);
