You can use reduce to create the result and operator in to check if the key exists: const obj = {“John”:44,”Sarah”:23,”Bob”:43,”Kate”:65,”Bill”:18}; const keys = [‘John’, ‘Bob’, ‘Kate’, ‘Bill’, ‘Fred’]; const result = keys.reduce((acc, el) => { if (el in obj) acc[el] = obj[el]; return acc; }, {}); console.log(result); Another approach is to convert the object … Read more

[Solved] PHP in array not working

The reason I can think of why this returns ERROR: if (in_array(array(‘string’, ‘id’), array(‘string’, ‘id’))) { echo ‘IN ARRAY’; } else { echo ‘ERROR!’; } is because PHP is checking each of the haystack’s values against the needle itself. Suppose you have 2 arrays like so: $a = array(‘string’, ‘id’); $b = array(‘string’, ‘id’); $a … Read more

[Solved] What is the simplest way to access array (not vector) element from middle to outermost?

by

An algorithm to list the elements from innermost to outermost is to pull off the last and first entries (pop and shift) in the array in alternation until no elements are left, then reverse the list of what you have pulled off. This works for odd and even-length arrays naturally. For example, 1,2,3,4,5,6 1,2,3,4,5 6 … Read more
