ViewsThe left-hand side of an 'in' expression must be a private identifier or of type 'any', 'string', 'number', or 'symbol'
How to fix this type error , even that i already define a String type to key parameter.
function checkIsExistObjectKeys(object: Object, key: String): Boolean {
return key in object;
}
console.log(
checkIsExistObjectKeys(
{
name: "john",
lastName: "Francois",
},
"name"
)
);
