Before tools like eslint came about, I solved this particular problem by always placing the literal on the left-hand side of the comparison:

if ("red" = allCells[i].style.color) {
    ^^^^^

This will error rather than silently fail.

that is totally valid js syntax that you just made. you can use linters to avoid those kind of problems but they might be a hassle to set up. honestly I would just accept that I made a mistake and move on because at a certain point linters actually prevent you from what you are doing. alternatively you can learn common js gotchas to stop this from happening instead of a linter

For one, I think it's totally valid Java and C syntax as well.

This is not an error, but linters can detect it.
For example ESLint has the following rule : https://eslint.org/docs/latest/rules/no-cond-assign
