regex index problem

[kenyipp]

I would like to exclude key with start of "_"
camelcaseKeys(object, { deep: true, exclude: [/^\_/ig] });
However, I found that some of keys has not follow that rule because the lastIndex of the regex has changed when it test the keys one by one and make it fail to test.
I have rewrite the "has" function to solve this problemfunction has(array, key) { return array.some(x => { if (typeof x === 'string') return x === key; else { x.lastIndex = 0; return x.test(key) } }); }
I am wondering if there has any better solution and if it can fix it in next version. thanks
