How does lodash.isLength work?
lodash.isLength is a function in the lodash library that checks if a value is a valid array-like length, meaning it is a non-negative integer less than or equal to the maximum safe integer value. If the value is a valid length, the function returns true; otherwise, it returns false.
Ai Example
1 2 3 4 5 6const _ = require("lodash"); console.log(_.isLength(5)); // true console.log(_.isLength(Number.MAX_SAFE_INTEGER + 1)); // false console.log(_.isLength("1")); // false console.log(_.isLength(null)); // false
In this example, we import the lodash library and use the isLength method to check whether various values are valid lengths. The method returns true if the value is a valid length, which is defined as a non-negative integer that is less than or equal to MAX_SAFE_INTEGER. The method returns false otherwise.
