Merge an array to the end of another array. The arrays can contain any types

Remove item from array.

Replace (part of) an array with items from another array.

Removes duplicate items from an array (uses Lodash uniq method). Note: This method does not supports nested arrays.

ArrayUtils.uniq([2, 1, 2]);
// => [2, 1]

Search for an element in an Array.

ArrayUtils.indexOf(['a', 'ab', 'abc'], 'ab');
// => 1

ArrayUtils.indexOf([[1, 2], null, [1, 3], undefined, 'a'], [1, 3], 0,
 (a, b) => ((a === b) || (a && b && a.toString() === b.toString())));
// => 2

Execute javascript function with given arguments. If the execution fails, return a default value.

let value = 2
LangUtils.scriptExecute(x => x * x, 0, value) //=> 4

Verify if a given value is an array.

Verify if a given value is a boolean.

Verify if a given value is a date.

Verify if a given value is a HTML element.

Verify if a given value is an empty value (uses Lodash isEmpty method). Checks if value is an empty object, collection, map, or set.

Verify if a given value is a function.

Verify if a given value is a number.

Verify if a given value is a number like.

Verify if a given value is an object like or not.

Verify if a given value is a plain object or not.

Verify if a given value is a regular expression or not.

Verify if a given value is a true value or not.

Verify if a given value is a string or not.

Verify if a given value is undefined or not.

Create a shallow clone object (uses Lodash clone method).

Create a deep clone object (uses Lodash cloneDeep method).

Performs a deep comparison between two values to determine if they are equivalent (uses Lodash isEqual method).

Note: This method supports comparing arrays, array buffers, booleans, date objects, error objects, maps, numbers, Object objects, regexes, sets, strings, symbols, and typed arrays. Object objects are compared by their own, not inherited, enumerable properties. Functions and DOM nodes are not supported.

var object = { 'user': 'fred' };
var other = { 'user': 'fred' };

LangUtils.isEqual(object, other);
// => true

object === other;
// => false

Get a value from a JSON object at a given path.

LangUtils.query({'a': ['b', 'c']}, 'a[1]');
//=> 'c'

LangUtils.query({'a': ['b', 'c']}, ['a', 1])
//=> 'c'

Filter out keys from an object.

LangUtils.omitDeep({a: "a", b: "b", c: {b: "b", d: {b: "b", f: "f"}}}, "b");
//=> {a: "a", c: {d: {f: "f"}}}

Verify if a window object is available.

Verify if a given value is an integer.

Create an array of keys from a plain object.

Create an array of values from a plain object.

Verify if a given key is present in an object.

Get a value from an object for a given key, if the key is not present return default value.

Verify if all elements of a given array are plain objects.

ObjectUtils.isPlainObjectArray([{h: 'h'}, [{k: 'k'}]]);
// => false

ObjectUtils.isPlainObjectArray([{h: 'h'}, [{k: 'k'}]], true);
// => true

Merge one object into another.

let toDict = {a: '1', b: {c: '1', e: null}, f: [{g: '1'}] };
let fromDict = {b: {c: '2', d: '2', e: '2'}, f: [{g: '2'}] };
ObjectUtils.merge(toDict, fromDict);
// => toDict is updated as {a: '1', b: {c: '2', d: '2', e: '2'}, f: [{g: '2'}]}

let toDict = {a: '1', b: {c: '1', e: null}, f: [{g: '1'}] };
let fromDict = {b: {c: '2', d: '2', e: '2'}, f: [{g: '2'}] };
ObjectUtils.merge(toDict, fromDict, true, true, true, true);
// => toDict is updated as {a: '1', b: {c: '1', d: '2', e: '2'}, f: [{g: '1'}, {g: '2'}]}

let toDict = {a: '1', b: {c: '1', e: null}, f: [{g: '1'}] };
let fromDict = {b: {c: '2', d: '2', e: '2'}, f: [{g: '2'}] };
ObjectUtils.merge(toDict, fromDict, true, true, false, true);
// => toDict is updated as {a: '1', b: {c: '1', d: '2', e: null}, f: [{g: '1'}, {g: '2'}]}

Create a new promise with given data

Creates a new interpolated string with a string template and a data object.

StringUtils.interpolate('${a} ${b}', {a: 5, b: 3});
// => '5 3'
