I have an object (values). I want to select the field which startWith('fld_str_)and which contains an object(for this case the FLD_STR_102). I want to delete the entire object from the createValue array and place it in an object CreateFileValue. You can check the output

Example input:

const values = {
  ID: 748817,
  createValues: [{
      field: "FLD_STR_101",
      value: 'hello',
    },
    {
      field: "FLD_STR_102",
      fileName: "doc.pdf",
      value: {
        field: 'FLD_STR_102',
        fileName: 'bulletin_paie_avril.pdf',
        value: 'jkhkjhkhkjh'
      },
    }

  ]
}

Example output:

const values = {
  ID: 748817,
  createValues: [{
      field: "FLD_STR_101",
      value: 'hello',
    }

  ],
  createFileValues: {
    "field": "FLD_STR_102",
    "fileName": "bulletin_paie_avril.pdf",
    "value": "jkhkjhkhkjh"
  }
}

const values = {
  ID: 748817,
  createValues: [{
      field: "FLD_STR_101",
      value: 'hello',
    },
    {
      field: "FLD_STR_102",
      fileName: "doc.pdf",
      value: {
        field: 'FLD_STR_102',
        fileName: 'bulletin_paie_avril.pdf',
        value: 'jkhkjhkhkjh'
      },
    }

  ]
}

const res = () => {
  if (values.createValues.startsWith('FLD_STR_') && typeof values.createValues.startsWith('FLD_STR_') === 'object') {
    return {

    };

  }
}
};
console.log(res());

// build createFileValues structure
values.createFileValues = values.createValues.filter(v => v.field.startsWith("FLD_STR_") && typeof v.value === "object");
// filter the files out of createValues
values.createValues = values.createValues.filter(v => !values.createFileValues.includes(v));
console.log(values);

values.createValues.startsWith('FLD_STR_') isn't valid because createValues is an array. You'll need to iterate over values.createValues in order to check each field.startsWith('FLD_STR_') and if value is an object (see How to detect if a variable is a pure javascript object for an example of this).

const values = {
  ID: 748817,
  createValues: [{
      field: "FLD_STR_101",
      value: 'hello',
    },
    {
      field: "FLD_STR_102",
      fileName: "doc.pdf",
      value: {
        field: 'FLD_STR_102',
        fileName: 'bulletin_paie_avril.pdf',
        value: 'jkhkjhkhkjh'
      }
    }
  ]
}

const res = () => {
  var newResult = {
    ID: values.ID,
    createValues: []
  };
  
  values.createValues.forEach(function(item) {
    var newCreateValue = {};
    
    if (item.field.startsWith('FLD_STR_') && item.value.constructor.name === "Object") {
      newCreateValue.field = item.value.field;
      newCreateValue.value = item.value.value;
      newCreateValue.fileName = item.value.fileName;
      
      // if this is a createFilesValue, add it as a new key/value to the newResult object
      newResult.createFileValues = newCreateValue;
    } else {
      newCreateValue.field = item.field;
      newCreateValue.value = item.value;
      
      // if this is an existing createValues, add it to the createValues array
      newResult.createValues.push(newCreateValue);
    }
  });
  
  return newResult;
};
console.log(res());

This should work

const values = {
  ID: 748817,
  createValues: [{
      field: "FLD_STR_101",
      value: 'hello',
    },
    {
      field: "FLD_STR_102",
      fileName: "doc.pdf",
      value: {
        field: 'FLD_STR_102',
        fileName: 'bulletin_paie_avril.pdf',
        value: 'jkhkjhkhkjh'
      },
    }

  ]
}

const res = (data) => {
  let oldCreateValues = data.createValues;
  let oldCreateFileValues = data.createFileValues;
  
  let newCreateValues = [];
  let newCreateFileValues = oldCreateFileValues && Array.isArray(oldCreateFileValues) ? oldCreateFileValues : [];
  if (oldCreateValues && Array.isArray(oldCreateValues)) {
    oldCreateValues.forEach(item => {
        if (item.field.startsWith('FLD_STR_') && item.value && typeof item.value === 'object') {
        newCreateFileValues.push(item);
      } else {
        newCreateValues.push(item);
      }
    });
  }
  
  data.createValues = newCreateValues;
  data.createFileValues = newCreateFileValues;
  
  return data;
};

console.log(res(values));
