How does ajv.compile work?

ajv.compile is a function that takes a JSON schema and compiles it into a validation function that can be used to validate data against that schema. The resulting validation function can be called with a data object as its argument, and will return a boolean indicating whether or not the data is valid according to the schema. The compiled validation function is optimized for performance, so it can be used to efficiently validate large amounts of data.

const Ajv = require("ajv");
const ajv = new Ajv();

const schema = {
  type: "object",
  properties: {
    name: {
      type: "string",
      maxLength: 30,
    },
    age: {
      type: "number",
      minimum: 18,
    },
  },
  required: ["name", "age"],
  additionalProperties: false,
};

const validate = ajv.compile(schema);

const data1 = { name: "John", age: 25 };
const data2 = { name: "Alice", age: "twenty-five" };

console.log(validate(data1)); // true
console.log(validate(data2)); // false

In this example, ajv.compile() is used to create a validation function called validate based on the JSON schema defined in the schema object. This function can then be used to validate data against the schema.
