i want to ask if it’s possible to do this:
const map1 = new Map(); map1.set('1', "led"); map1.set('2', "zeppelin"); const map2 = new Map(); map2.set('1', "led"); map2.set('2', "floyd");
I want to compare these 2 maps. I want to have a console.log() with the deferences of the maps.
Finally if the maps are the same and i add in map1 a new set
map1.set('3', "plant");
I want a log to tell me which is the new pair of kay-val
Thank you

const map1 = new Map(); map1.set('1', "led"); map1.set('2', "zeppelin"); const map2 = new Map(); map2.set('1', "led"); map2.set('2', "floyd"); let isSame = true; map1.forEach(function(val, key){ if(map2.get(key) != val){ console.log('map1.'+key+' = '+val +' | map2.' + key + ' = '+map2.get(key)); isSame = false; } }) if(isSame){ map1.set('3', "plant"); map1.forEach(function(val, key){ console.log('map1.'+key+' => '+val); }) }
