let arr = [
{value: 'L7-LO', name: 'L7-LO'},
{value: '%L7-LO', name: '%L7-LO'},
{value: 'L7-LO', name: 'L7-LO'},
{value: '%L7-LO', name: '%L7-LO'},
{value: 'L7-L3', name: 'L7-L3'},
{value: '%L7-L3', name: '%L7-L3'},
{value: 'LO-L3', name: 'LO-L3'},
{value: '%LO-L3', name: '%LO-L3'}
];
let obj = {};
const unique = () => {
let result = [];
arr.forEach((item, i) => {
obj[item['value']] = i;
});
for (let key in obj) {
let index = obj[key];
result.push(arr[index])
}
return result;

var filterArray = courseArray.reduce((accumalator, current) => {
if(!accumalator.some(item => item.id === current.id && item.name === current.name)) {
accumalator.push(current);
}
return accumalator;
},[]);
console.log(filterArray)
