Value of Local Storage setItem won't be printed either in getItem or in console.log

JavaScript
1

In Microsoft Edge version 120.0.2210.91 (Official build) (64-bit) I try to set and get a value with the Local Storage API.

Setting

localStorage.setItem["first_example"] = 1;

1

Getting

localStorage.getItem["first_example"];

undefined

console.log(localStorage["first_example"]);

undefined

undefined

My question

Why did I get one undefined in the getItem command and two undefined in the console.log command?

Maybe you should use round brackets and not square ones?

localStorage.setItem("first_example") = 1;

Uncaught TypeError: Failed to execute ‘setItem’ on ‘Storage’: 2 arguments required, but only 1 present.

localStorage.setItem{"first_example"} = 1;

Uncaught SyntaxError: Unexpected token ‘{’

localStorage.setItem("first_example", 1);

Dear Dave, thanks.

localStorage.getItem("first_example");

Which is what you’re looking for? I don’t get the output from the undefined. You can’t output a set.

  • Setters add/update a value
  • Getters return a value.

I know, I meant that getting the following output from the getter:

I just meant to show the entire process from start to finish (including the undefined console output for the setter), was fine :slight_smile:
