The most popular correct method, is called the Fisher Yates shuffle, and was introduced in data science as early as 1938! In JavaScript the method can be translated to this:

The Fisher–Yates shuffle, in its original form, was described in 1938 by Ronald Fisher and Frank Yates in their book Statistical tables for biological, agricultural and medical research. Their description of the algorithm used pencil and paper; a table of random numbers provided the randomness. The basic method given for generating a random permutation of the numbers 1 through N goes as follows:
