This LIB has several Helpers/Users already created to avoid breaking the head making the same logic.

Functions list

• isNumber
• listener
• asyncMapPromise
• convertHexToRGBA
• initialLetter
• removeSpecialCharacters
• trimText
• removeSpaceInText
• goWhatsapp
• isEmpty
• fixNullToNumber

isNumber

Function that checks if the parameter is a number.

masterTool.isNumber(value)

The default value is null and the return is boolean type.

masterTool.isNumber(1) // true
masterTool.isNumber(true) // false
masterTool.isNumber('text') // false
masterTool.isNumber({ a: 1, b: 2}) // false
masterTool.isNumber(null) // false

listener

Function that centralizes the use of addEventListener.

masterTool.listener(scope, event, callback, wantsUntrusted)

Params/Return:

• Params:
  • scope: The values accepted are window or document, default is document. If you will run on Window or Document.
  • event: The values accepted are the same as type on addEventListener, see the list here.
  • callback: Function to be executed.
  • wantsUntrusted: Default is false. Used to specify whether the event can be triggered by untrusted content, it is an optional option and present in the eventListener.
• Return: It returns nothing.

// Window
masterTool.listener('window', 'load', () => {
  console.log('Hello my window')
})

// Document
masterTool.listener('document', 'load', () => {
  console.log('Hello my document')
})

// HTML element
const buttonElement = document.querySelector('#close-button')
const cbFunction = () => {
  console.log('Hello my others')
}

masterTool.listener('others', 'load', cbFunction, false, buttonElement)

asyncMapPromise

Function created to do Async in .map of javascript. This function is asynchronous.

masterTool.asyncMapPromise(itens, callback)

Params/Return:

• Params:
  • itens: array of items, default value is an empty array ([]).
  • callback: Function to be executed.
• Return: Returns a new array of items, as the callback function returns

const array = ['1', '2', '3', '4']
const cbFunction = (item, index, array) => item === '2'
const newArray = await $masterTool.asyncMapPromise(array, cbFunction)

Obs.: The .map in JavaScript by default will return undefined if there is a conditional logic (if) inside it to return only if the condition passes, needing to run a .filter to clean the unwanted data (undefined), in asyncMapPromise() it works the same, here's an example:

const array = ['1', '2', '3', '4']

// in JavaScript
const newArray = array.map((item, index, array) => {
  if (item === '2') return item
})
console.log(newArray) // [undefined, '2', undefined, undefined]
newArray.filter(item => item !== undefined) // ['2']


// asyncMapPromise()
const newArray2 = await $masterTool.asyncMapPromise(array, (item, index, array) => {
  if (item === '2') return item
})
console.log(newArray2) // [undefined, '2', undefined, undefined]
newArray2.filter(item => item !== undefined) // ['2']
