});как переписать код, чтобы не использовать let, а всегда увеличивать на единицу внутри функции?В примере как раз Ваш случай:
const list = [
'main',
'main-footer',
'main-header',
'main-content',
];
list.reduce((p, item) => p.then(() => funcOne(item)), Promise.resolve());const sum = Object.values(appData.optionalExpenses).reduce((s, v) => s + v, 0);
console.log(sum);export default function({ types: t }) {
return {
visitor: {
Identifier(path) {
if(path.isIdentifier({ name: 'test' })) {
path.parentPath.get('init').node.value = 777
}
}
}
};
};let observer = new IntersectionObserver(
(entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting) {
entry.target.lastElementChild.classList.add(classes.image + "_active");
entry.target.lastElementChild.style.opacity = entry.intersectionRatio;
} else {
entry.target.lastElementChild.classList.remove(classes.image + "_active");
}
});
},
{
threshold: [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1]
}
);
block.forEach((value) => observer.observe(value));function alertThis() {
alert(this);
}
alertThis.call('text');el_table.contains(e.target)всегда вернет true, а следовательно мы никогда не попадем в такой if
