How can i solve "typeerror: cannot read property 'x' of undefined" in javascript?

Example:

let obj;
console.log(obj.property);

This error means you're trying to access a property on an object that doesn't exist or is undefined.

Solution: Ensure the object is initialized and the property exists.

let obj = { property: "value" };
console.log(obj.property);
