So if you play Minecraft, you know that Mojang Studios always releases test snapshots/beta, depending on the Minecraft edition which you have. What is the difference between snapshots and betas? Here I will tell you.
Snapshots are like “experimental” instances of Minecraft for the Java edition only. Snapshots usually ship before a Bedrock Beta.
The bedrock betas are like snapshots but on Bedrock edition and you can enroll to get the Bedrock beta version on any device (excluding iOS a), in order to gain access to the Bedrock Beta features and more experimental worlds toggles.
