Conclusion first

We cannot break in forEach loop

What are the alternatives

• for of : for...of - JavaScript | MDN

=> You might get eslint error
no-restricted-syntax - Rules - ESLint - Pluggable JavaScript linter

• some or every

Here is the case with some()
Array.prototype.some() - JavaScript | MDN

returning true break the loop 👍
