Have a look at Array.reduce and Object.values.ray– ray2020-09-02 00:43:36 +00:00Commented Sep 2, 2020 at 0:43

Use Array#reduce to accumulate your object-data. Foreach object take from the values the first and add a new property with this name to the accumulated object with the value from the second object-value.
let array = [ { key1:'value1', key2:'value2' }, { key3:'value3', key4:'value4' }];
let res = array.reduce((acc, cur) => {
values = Object.values(cur);
acc[values[0]] = values[1];
return acc;
}, {});
console.log(res);

Assuming the inner objects always have 2 keys:
const arr = [ { key1:'value1', key2:'value2' }, { key3:'value3', key4:'value4' }]
const obj = {};
for (const innerObj of arr) {
const values = Object.values(innerObj);
obj[values[0]] = values[1];
}
console.log(obj) // { value1: 'value2', value3: 'value4' }
Note: you're question assumes an order for the keys in the inner objects, but that may not be guaranteed
