在程式設計中,如果我們想在滿足一個或多個特定條件時執行程式碼,那麼在這種情況下,我們會使用稱為if語句的東西。假設我們有一個整數陣列,我們想檢查陣列中是否存在數字20。我們通過在if語句中新增一個條件來做到這一點,如下所示。 vararr=[5,25,70,62,20,89];arr.forEach(num=>{if(num==20){// do som...
The above example uses the%operator, which returns the remainder when the number preceding it is divided by the number following it. If the remainder when divided by2is0, the number is even. Example: Filtering Strings Using Multiple Conditions Below, an array of strings is defined and filtered...
Filter Multiple Conditions in JavaScript Arrays are a type of JavaScript object with a fixed numeric key and dynamic values. JavaScript provides several built-in methods to access and manipulate these array elements. The filter() method generates a new array from the original array with all element...

If multiple cases matches a case value, thefirstcase is selected. If no matching cases are found, the program continues to thedefaultlabel. If no default label is found, the program continues to the statement(s)after the switch. Strict Comparison ...
eslint: one-var jscs: disallowMultipleVarDecl Why? 这种方式很容易去声明新的变量,你不用去考虑把;调换成,,或者引入一个只有标点的不同的变化。这种做法也可以是你在调试的时候单步每个声明语句,而不是一下跳过所有声明。 // bad const items = getItems(), goSportsTeam = true, dragonball = 'z'; /...
For multiple conditions, you should consider using the switch statement if the conditions are based on string or numeric value equivalency: switch (expression) { case valueA: // statements to execute if expression evaluates to valueA break; // skip over default case valueB: // statements to ...
This is not recommended, since you might end up loading polyfills multiple times. Might still be nifty for small applications or quick POCs.Use of Unicode Characters / UTF-8:The 14 standard fonts in PDF are limited to the ASCII-codepage...
