Question

1C-Bitrix

Hello, tell me how to make the output of one object with 57 elements, and not first 50 and then another rest of 7. It is
necessary to overwrite, and not overwrite each time using map

getField() {
      BX24.callMethod('entity.item.get', {
            ENTITY: 'wheelfortune', SORT: {'ID': 'ASC'}
          },
          (result) => {
            let sections = result.data();

            this.fields = sections.map((field) => ({
              ID: field.ID,
              NAME: field.NAME,
              SECTION: field.SECTION,
              'IS_EDITFIELD': false
            }))
            console.log(this.fields);
            if (result.more()) {
              result.next();
            }
          });
    },

Answer 1

based on WapSter 's answer , did this

getField() {
      BX24.callMethod('entity.item.get', {
            ENTITY: 'wheelfortune', SORT: {'ID': 'ASC'}
          },
          (result) => {
            let sections = result.data();
            let newSections = sections.map((field) => ({
              ID: field.ID,
              NAME: field.NAME,
              SECTION: field.SECTION,
              'IS_EDITFIELD': false
            }))
            this.fields = newSections.concat(this.fields);
            if (result.more()) {
              result.next();
            }
          });
    },

getField() {
      BX24.callMethod('entity.item.get', {
            ENTITY: 'wheelfortune', SORT: {'ID': 'ASC'}
          },
          (result) => {
            let sections = result.data();

            const newSections = sections.map((field) => ({
              ID: field.ID,
              NAME: field.NAME,
              SECTION: field.SECTION,
              'IS_EDITFIELD': false
            }))
            this.fields.join(...newSections)
            console.log(this.fields);
            if (result.more()) {
              result.next();
            }
          });
    },
