When operators have the same precedence (like + and -), they are computed from left to right: letx =100/50*3; Try it Yourself » Operator Precedence Values Expressions in parentheses are computedbeforethe rest of the expression Function are executedbeforethe result is used in the rest of...
Learn the basics of the JavaScript Operators Precedence RulesEvery complex statement will introduce precedence problems.Take this:const a = 1 * 2 + 5 / 2 % 2The result is 2.5, but why? What operations are executed first, and which need to wait?Some operations have more precedence than the...
Table Operator precedence determines the order in which operators are evaluated. Operators with higher precedence are evaluated first. A common example: 3 + 4 * 5 // returns 23 The multiplication operator ("*") has higher precedence than the addition operator ("+") and thus will be evalua...
JavaScript is a good language, but we should pay attention to not make mistakes. Especially when working with operations, operator precedence plays a very important part. Operator precedence tell us which operators should and will go first in an operation—operators with higher precedence will go f...

log('Yup.'); }; } Never name a parameter arguments. This will take precedence over the arguments object that is given to every function scope. // bad function nope(name, options, arguments) { // ...stuff... } // good function yup(name, options, args) { // ...stuff... }...
// Operators have both a precedence (order of importance, like * before +) // and an associativity (order of evaluation, like left-to-right) // A table of operators can be found here // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence) //...
When new operators are added to JavaScript, they do not always fit naturally into this precedence scheme. The ?? operator (§4.13.2) is shown in the table as lower-precedence than || and &&, but, in fact, its precedence relative to those operators is not defined, and ES2020 requires ...
In JS, the equals and not equals operators are of lower precedence than less than et al. In Lua, all comparison operators are thesame precedence. Lua supportstail calls. Lua supportsassignment to a list of variables. While it isn't yet standard in Javascript, Mozilla's JS engine (and Ope...
Order of Precedence A regular expression is evaluated much like an arithmetic expression; that is, it is evaluated from left to right and follows an order of precedence. The following table contains the order of precedence of the regular expression operators, from highest to lowest. ...
