intval/src/index.js

Returns sensible integer value of a given variable. Unlike parseInt it will never return NaN and you can set a default value to be returned in case the variable is undefined! Hence you can write even cleaner code. So if it's supposed to be an integer, cas

/**
 * Returns the integer value of any given input value
 * @param {*} value - Input value
 * @param {number} [base] - The base
 * @param {*} [defaultValue] - The default value
 * @returns {number} - The integer value of the provided input value or of the defaultValue in case the input is undefined
