Discover how to iterate through an array following a map operation and generate a new array based on conditional statements

data.risk.scatterIndices.investments.map((el: any) => el.name) || []

I have a mapping function that generates an array like this:

["pension","realestate","balance","kupot"]

This is the condition I want to use to translate this array into a new array:

`
if(key === 'balance'){
    key = 'עוש ומזומן'
} else if(key === 'realestate'){
    key = 'נדלן'
} else if(key === 'pension'){
    key = 'פנסיה'
} else if(key === 'kupot'){
    key = 'קופות'
}
`

Expected output:

["קופות","עוש ומזומן","נדלן","פנסיה"]

How can I achieve this?

To transform the array elements, you can utilize the map function.

const arr = ['pension', 'realestate', 'balance', 'kupot']

const res = arr.map(key => {
  if (key === 'balance') {
    return 'עוש ומזומן'
  } else if (key === 'realestate') {
    return 'נדלן'
  } else if (key === 'pension') {
    return 'פנסיה'
  } else if (key === 'kupot') {
    return 'קופות'
  } else {
    return 'N/A'
  }
})

console.log(res)

To convert values in an array, simply utilize a "For" loop as demonstrated below:

for(let i=0; i < array.length; i++){

  switch (array[i]) {
    case "pension":
      array[i] = 'פנסיה';
      break;

    // Include more cases in the switch statement for additional conversions
  }
}

To simplify the process, you can create an object with replacements and map through the array to replace values if they exist in the object.

const
    replacements = { balance: 'עוש ומזומן', realestate: 'נדלן', pension: 'פנסיה', kupot: 'קופות' },
    array = ["pension", "realestate", "balance", "kupot", "some value"],
    result = array.map(k => replacements[k] || k);

console.log(result);
