What does 'typeerror: cannot read property 'x' of undefined' mean in javascript?

This error indicates that you are trying to access a property on an undefined object.

Example:


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

Solution:


let obj = { property: 'value' };
console.log(obj.property);
Always ensure the object is defined and initialized before accessing its properties.
