I'm currently in development of a minesweeper game and I want to store the value of a 'noWins' variable into local storage once the game is won (I have a boolean called wonGame which is set to true when the game is won).
How can I do this?

To store data in localStorage, you use the setItem() function. This function takes two parameters, the item key and a value.
if(wonGame == true){
localStorage.setItem('noWins', 'value');
}
In response to your comment,
local storage stores values as strings, therefore the value has to be converted to a number using parseInt. The first value for noWins would be set to 0
so the new code should be
//set the initial value of noWins to 0
localStorage.setItem('noWins' , 0)
if (wonGame === true){
var winning = parseInt(localstorage.getItem("noWins");
//increment value
localStorage.setItem("winning", winning++)
}
Note that "winning" is just a variable I created

How would I increment this? Would it be something along the lines of : localStorage.getItem('noWins') = number(localStorage.getItem('noWins')) +1 – Stephen Mar 05 '18 at 19:35
