25 lip 2024 · Change the line that calculates y so the box is 75px high, but the 75 is calculated using the numbers 25 and 3 and an arithmetic operator. Change the line that calculates x so the box is 250px wide, but the 250 is calculated using two numbers and the remainder (modulo) operator.
In my case (color-coding a percentage, nothing performance-critical), I quickly wrote this: function findColor(progress) { const thresholds = [30, 60]; const colors = ["#90B451", "#F9A92F", "#90B451"]; return colors.find((col, index) => { return index >= thresholds.length || progress < thresholds[index]; }); }
The greater than ( >) operator returns true if the left operand is greater than the right operand, and false otherwise. Try it. Syntax. js. x > y. Description.
In JavaScript, understanding comparisons and operators is important for effective scripting. This guide will delve into comparison operators, arithmetic operations, and string concatenation, ensuring a comprehensive grasp of these essential concepts.
We use comparison operators to compare two values and return a boolean value (true or false). For example, const a = 3, b = 2; console.log(a > b); // Output: true. Run Code. Here, we have used the > comparison operator to check whether a (whose value is 3) is greater than b (whose value is 2).
30 lip 2024 · Expressions and operators. This chapter describes JavaScript's expressions and operators, including assignment, comparison, arithmetic, bitwise, logical, string, ternary and more. At a high level, an expression is a valid unit of code that resolves to a value.
