Ways to transform a group of strings into an array of separate strings

Ways to transform a group of strings into an array of separate strings

function categorizeMember(data) {
  let resultArr = []
  let userData = [data]
  return userData.forEach(data => {
    data.map(data => {
      let category = (data[0] >= 55 && data[1] > 7) ? console.log("Senior") : console.log("Open");
      return category
    })
  })
}

the function above should categorize members as senior or open in this form

[ 'Open', 'Senior', 'Open', 'Senior' ]

however, the output I received was: Open Senior Open Senior

an example of the expected output:

input = [[18, 20], [45, 2], [61, 12], [37, 6], [21, 21], [78, 9]] 
output = ["Open", "Open", "Senior", "Open", "Open", "Senior"]

javascript arrays

Answer №1

To determine if a person is a 'Senior' or 'Open', you can simply map the desired strings based on the values of the left and right items within the nested arrays.

function checkMembershipStatus(data) {
    return data.map(([left, right]) => left >= 55 && right > 7 ? 'Senior' : 'Open');
}

const data = [[18, 20], [45, 2], [61, 12], [37, 6], [21, 21], [78, 9]];

console.log(checkMembershipStatus(data)); // ["Open", "Open", "Senior", "Open", "Open", "Senior"]

function checkMembershipStatus(data) {
    return data.map(([left, right]) => left >= 55 && right > 7 ? 'Senior' : 'Open');
}

const data = [[18, 20], [45, 2], [61, 12], [37, 6], [21, 21], [78, 9]];

console.log(checkMembershipStatus(data)); // ["Open", "Open", "Senior", "Open", "Open", "Senior"]

If you want to implement the code-template mentioned in the description, here is one way to solve it:

function checkMembershipStatus(data) {
  let statusArray = [];
  let userData = [data];
  userData.forEach(data => {
    data.map(memberData => {
      let status = (memberData[0] >= 55 && memberData[1] > 7) ? "Senior" : "Open";
      statusArray.push(status);
    });
  });
  return statusArray;
}

const data = [[18, 20], [45, 2], [61, 12], [37, 6], [21, 21], [78, 9]];
console.log(checkMembershipStatus(data)); // ["Open", "Open", "Senior", "Open", "Open", "Senior"]

However, the above solution involves redundant operations. A more efficient approach would be:

function checkMembershipStatus(data) {  
    return data.map(memberData => (memberData[0] >= 55 && memberData[1] > 7) ? "Senior" : "Open");     
}

const data = [[18, 20], [45, 2], [61, 12], [37, 6], [21, 21], [78, 9]];
console.log(checkMembershipStatus(data)); // ["Open", "Open", "Senior", "Open", "Open", "Senior"]
