Examples

"modifier": {
    "attribute": "minecraft:generic.attack_damage",
    "operation": "addition",
    "value": 9
}

This example will add 9.0 to the base value of the entity's minecraft:generic.attack_damage attribute. (For example: if the current base value is 1, the new base value will be 10 since 1 + 9 = 10) 

"modifier": {
    "attribute": "minecraft:generic.max_health",
    "operation": "multiply_base",
    "value": 2
}

This example will add the base value multiplied by the modifier value to the current base value of the entity's minecraft:generic.max_health attribute. (For example: if the current base value is 20, the new base value will be 60 since 20 + (20 * 2) = 60) 

"modifier": {
    "attribute": "minecraft:generic.movement_speed",
    "operation": "multiply_total",
    "value": 0.5
}

This example will multiply the total value of the entity's minecraft:generic.movement_speed attribute by 1.5, essentially increasing the total value by 50%. (For example: if the total value is 0.7, the new total value will be 1.05 since 0.7 * (1 + 0.5) = 1.05)
