4 Common Javascript Errors That You Encounter Every Day

1. 4 Common Javascript Errors That You Encounter Every Day JavaScript, a prominent text-based programming language, holds its status in the world of development technologies. It is a client and server-side language popular for creating interactive and interesting websites. However, neither languages nor developers are perfect; thus, encountering errors and resolving them is part of creating something significant. While working with JavaScript, developers may encounter several errors that eat up a lot of time. Therefor it is essential to comprehend common mistakes and use AI-powered software like Zipy that allows you to debug errors instantly. Let’s understand some of these errors. Range error A range error occurs when manipulation of arithmetic value lies outside the value range a data can represent. You can encounter a range error in multiple circumstances, and it is wise to usea JavaScript error tracking tool to increase its visibility. Some of the situations include: ●While specifying an array length that is either a floating number, negative or surpasses the maximum length a platform supports. ●Passing value to a certain function that lies outside the acceptable range of values. ●When a referenced variable is neither declared nor available in the current scope or script.

2. Type Error Type errors are one of the most common JavaScript errors a developer will encounter. Generally, you will come across type errors mentioned underneath, they are. ●Using an incorrect value type: This error results from executing an operation using an incompatible value. For instance, you might use a string to achieve a mathematical operation or call/label a non-function as a function. ●Using a non-existential value: This error will pop up on your screens if you use a value that does not exist. For instance, if you try to access a property when the object doesn’t exist. Syntax Error Syntax signifies a set of rules that regulates the structure of symbols, punctuations, and words used in programming languages. In JavaScript, a syntax error appears when the parser cannot understand certain code, mainly due to misusing keywords or type errors such as the absence or improper formatting of semicolons, quotation marks, or commas. URI Errors Just like a type error, you may regularly come across a URI error in JS. Encoding or decoding a URI (Uniform Resource Identifier) using encodeURIcomponent, decodeURLcomponent, encodeURI, or decodeURI functions with incorrect input is the reason behind URI error. The above functions convert URI’s special characters in a format that is easy to transmit over the web without complications. However, if you input a deformed URI or an invalid character, you may come across a URI error. Wrapping up Errors are just small hindrances to your big projects. You cannot avoid errors, but you can definitely use a JavaScript error monitoring tool to increase their visibility, ultimately leading to a quicker solution.
