Need some help understanding the spread syntax

Hmm on my phone and didn’t open the link but I’ll try to explain (apologies if I glossed over something and misanswer) What I see is this: { ...grid[row][col], value: value } What this basically means is spread the result of grid[row][col] THEN set value to value. Meaning even if the grid part returned 5 if value is 4 its overwriting it. You see this a lot in redux. You spread the previous state onto a new object but in that new object you set some new values. Another example, switch the order of { value: value, ...grid[row][col], } And see what happens. Hopefully that helps Edit: spreading an object works how you thought it would but it dosent create a nested object. It just sets the key and value in the new object. Which then gets overwritten because you’re setting value in the same object More on reddit.com
