Exploring how to manipulate strings in Java Script with the Slice method

Hey there, I have a string that looks like this: 

[{"list":"Gross Motor Skills""value":"8"}{""list":"Sorting""value":"8"}
 {""list":"Grouping""value":"8"}{""list":"Drawing""value":"8"}
 {""list":"Observations""value":"6"}{""list":"Writing""value":"7"}]"

My goal is to remove all the extra information and format it into an array like this: 

Gross Motor Skills 8
Sorting 8 
etc.

I've tried using splice and split methods but couldn't figure it out. Can anyone assist me with this? Thanks in advance.

Answer №1

If you structure your array/objects properly, you can utilize the Object.values method to extract the values.

var data = [{ type: "Fruits", quantity: "10" }, { type: "Vegetables", quantity: "5" }, { type: "Dairy", quantity: "8" }, { type: "Grains", quantity: "6" }],
    extractedValues = data.map(item => Object.values(item));

console.log(extractedValues);

Answer №2

I need to streamline the content and convert it into an array like this:

Gross Motor Skills 8
Sorting 8 
etc.

Utilize map and join

var result = arr.map( data => data.category.concat( data.score ) ).join( "\n" );

Example

var arr = [{
    "category": "Gross Motor Skills",
    "score": "8"
  }, {
    "category": "Sorting",
    "score": "8"
  },
  {
    "category": "Grouping",
    "score": "8"
  }, {
    "category": "Drawing",
    "score": "8"
  }, {
    "category": "Observations",
    "score": "6"
  }, {
    "category": "Writing",
    "score": "7"
  }
];
var result = arr.map( data => data.category + " - " + data.score ).join( "\n" );
console.log( result );

If you want the array as output, then you can skip using join

var result = arr.map( data => data.category + " - " + data.score );
