I would like to add a marker to the map using the form. Can anyone help me? Installing the map works. I want to display markers after entering x and y, and read this data from the table. I have 2 inputs, one for X and the other for Y after clicking "add" I add this data to the table and I have 2 objects, etc ... but only one marker from state.items is displayed on the map, although I have more coordinates in the table.I know that the componentDidMount () method is only run once and here is the problem.Please Help
That is the most important skill to have when writing code.
Basically, press F12 in your browser and your browser's developer tools will open. First, check the console to see if you have errors. Then you can click in the line of code you want to test and create a breakpoint.
Too much to go into here, but yes, you'll want to learn to debug.
