Iterating over Typescript Map

Question

You could use Map.prototype.forEach((value, key, map) => void, thisArg?) : void instead

Use it like this:

myMap.forEach((value: boolean, key: string) => {
    console.log(key, value);
});

es6

for (let [key, value] of map) {
    console.log(key, value);
}

es5

for (let entry of Array.from(map.entries())) {
    let key = entry[0];
    let value = entry[1];
}

Just use Array.from() method to convert it to an Array:

myMap : Map<string, boolean>;
for(let key of Array.from( myMap.keys()) ) {
   console.log(key);
}

Using Array.from, Array.prototype.forEach(), and arrow functions:

Iterate over the keys:

Array.from(myMap.keys()).forEach(key => console.log(key));

Iterate over the values:

Array.from(myMap.values()).forEach(value => console.log(value));

Iterate over the entries:

Array.from(myMap.entries()).forEach(entry => console.log('Key: ' + entry[0] + ' Value: ' + entry[1]));

This worked for me. TypeScript Version: 2.8.3

for (const [key, value] of Object.entries(myMap)) { 
    console.log(key, value);
}
