How to Display the Entire Object in Console in React Native

How do I print out my object array in React Native Expo?

React JS : Logging the array items in the console

Use comma instead of +.

console.log("listofItems: ",  listItems); 

This way javascript wont try to convert it to string, and chrome console would let you expand your array of objects

React - Can console log object, but not specific property of said object

When your component is mounted, pokeList is an empty array.

React will run the following block before the useEffect hook has finished running:

const specificPokemon = pokeList.find((pokemon) => {
  return pokemon.name === pokeName.pokemon_name;
});

console.log(specificPokemon);
console.log(specificPokemon.name);

As long as your array is empty, specificPokemon will be undefined and calling specificPokemon.name will trigger your error.

Beware with console.log, its behavior is not always synchronous.

You might think specificPokemon is properly defined because console.log won't necessarily show undefined.

To verify this, use console.log(JSON.stringify(specificPokemon));.

why i got [object object ]

Use JSON.stringify instead .toString
This question might help you What's the difference in using toString() compared to JSON.stringify()? understand the difference

let x = {a: 123, b: 321};console.log("toString", x.toString());console.log("stringified", JSON.stringify(x));
