Mapify is a 0.7KB standalone module for map iteration over Arrays and Objects, in the same fashion Array.prototype.map works, but also includes Object iteration support and is faster than .map itself.
Creates a new Array with the results of calling a provided function on every element in this Array.
mapify(arr, callback[, thisArg]);
// Callback parameters
// currentValue: The current element being processed in the array.
// index: The index of the current element being processed in the array.
// array: The array being mapped.
// thisArg (optional)
// Value to use as this when executing callback.var mapped = mapify([1, 3, 9], function (currentValue, index, array) {
return currentValue * currentValue;
})
console.log(mapped); // 1, 9, 81Creates a new Object with the results of calling a provided function on every property in this Object.
mapify(obj, callback[, thisArg]);
// Callback parameters
// currentValue: The current element being processed in the object.
// propName: The name of the current property being processed in the object.
// object: The object being mapped.
//
// thisArg (optional)
// Value to use as this when executing callback.var mapped = mapify({ a: 1, b: 2, c: 3 }, function (currentValue, propName, object) {
return currentValue * currentValue;
})
console.log(mapped); // { a: 1, b: 4, c: 9 }To install Mapify into your project using Bower, use the GitHub repository hook:
bower install https://github.com/toddmotto/mapify.git
Drop your files into your required folders, make sure you're using the files from the dist folder, which is the compiled production-ready code. Ensure you place the script before the closing </body> tag so the DOM tree is populated when the script runs.
