map.forEach( callback(value, propName ) )

forEach iterates through the map instance, calling a function for each property value and key.

map.forEach(function(value, propName){ ... });

Parameters

  1. callback {function(value, propName)}:

    The function to call for each property The value and key of each property will be passed as the first and second arguments, respectively, to the callback. If the callback returns false, the loop will stop.

Returns

{can-define/map/map}:

The map instance for chaining.

Use

Example

var names = [];
new DefineMap({a: 'Alice', b: 'Bob', e: 'Eve'}).forEach(function(value, key) {
    names.push(value);
});

names; // ['Alice', 'Bob', 'Eve']

names = [];
new DefineMap({a: 'Alice', b: 'Bob', e: 'Eve'}).forEach(function(value, key) {
    names.push(value);
    if(key === 'b') {
        return false;
    }
});
