Javascript Comparisons

Often you want to compare a value of one variable with one of another variable, or the value of a variable against a literal value, for example the value in an if-statement.

Example for a comparison is if you want to compare the value of the day of week to “Sunday”, you can do this by checking todaysDate == “Thursday”.

Don’t mix up ‘=’ with ‘==’, the first is an assignment, the second one is a comparison.
