Is `if (condition = value)` the correct syntax for comparison?

Question

If if((hit.transform != transform) means if hit.transform is Not transform, then how do I check if the statement Is correct. if(hit.transfor

Answer 1

You need two equals signs for equality

if (hit.transform == transform)

Note that that will allow all sorts of implicit conversions, so you should really use three equals signs—identity equality or strict equality:

if (hit.transform === transform)

Note that a single equals sign is assignment.

x = y;

Now x has the value of y.

Your statement

if(hit.transform = transform)

Assigns hit.transform to the value of transform, then tests to see if the result of this expression, which will be the same as hit.transform's new value, is "truthy"
