Understanding the array methods Array.some() and Array.every() in JavaScript

// We have a sample Array of persons from country ABCconst sampleArray = [  {    name: "John",    occupation: "Doctor",    age: 31,    sex: "male",    country: "ABC"  },  {    name: "Jane",    occupation: "Doctor",    age: 26,    sex: "female",    country: "ABC"  },  {    name: "Roger",    occupation: "Engineer",    age: 28,    sex: "male",    country: "ABC"  },  {    name: "Riya",    occupation: "Engineer",    age: 32,    sex: "female",    country: "ABC"  }]// I want to find out if all of them are from country "ABC"const countryCheck = sampleArray.every(person => {  return person.country === "ABC"})console.log("All are from the same country? ", countryCheck)// I want to check if all are engineersconst engineerCheck = sampleArray.every(person => {    return person.occupation === "Engineer"})console.log("All are Engineers? ", engineerCheck)// I want to check if at least some women are engineersconst womenEngineers = sampleArray.some(person => {    return person.occupation === "Engineer" && person.sex === "female"})console.log("Do we have at least some women engineers?", womenEngineers)// I want to check if any of them are advocatesconst lawyerCheck = sampleArray.some(person => {return person.occupation === "Lawyer"})console.log("Do we have any lawyers?", lawyerCheck)

// SyntaxArray.every(callback)const callback = (currentElement, index, array) => {  // currentElement - current item in the array that we are iterating over over  // index - index of the current item - optional  // array - array that we are iterating over - optional} // example usageArray.every((currentElement) => {    return currentElement > 1})

// SyntaxArray.some(callback)const callback = (currentElement, index, array) => {  // currentElement - current item in the array that we are iterating over over  // index - index of the current item - optional  // array - array that we are iterating over - optional} // example usageArray.some((currentElement) => {    return currentElement > 1})
