Lodash
const [a, b] = _.partition(tabl, e => e === 900); const newArr = [...a,...b];
Reduce
const newArr = tabl.reduce((prevArr, currVal) => {if(currVal.key === 900) {return [currVal, ...prevArr]} else {return [...prevArr, currVal]}}, [])
2 Filter
const a = tabl.filter(e => e === 900); const b = tabl.filter(e => e !== 900); const newArr = [...a,...b];
