We look at the defaultArray.prototype.sortbehavior and discuss how you can do case insensitive string sorting. const foo =['Alpha','beta','Gamma','delta']; foo.sort((a, b)=>a.toLowerCase().localeCompare(b.toLowerCase())); foo.forEach(x=>console.log(x));/*"Alpha" "beta" "del...
Both includes() and indexOf()function are case sensitiveconst array = ['MANGO']; array.includes('mango'); // false array.indexOf('mango') !== -1; // false You can make it case insensitive by changing the case of the array

类似地,通过new Array()创建的对象使用Array.prototype作为它们的原型,通过new Date()创建的对象使用Date.prototype作为它们的原型。初学 JavaScript 时可能会感到困惑。记住:几乎所有对象都有一个原型,但只有相对较少的对象有一个prototype属性。具有prototype属性的这些对象为所有其他对象定义了原型。 Object.prototype是...
EZArray 的实例表现得像普通数组,我们可以使用继承的方法和属性,比如push()、pop()和length。但我们也可以使用子类中定义的first和last getter。不仅实例方法像pop()被继承了,静态方法像Array.isArray也被继承了。这是 ES6 类语法启用的一个新特性:EZArray()是一个函数,但它继承自Array(): 代码语言:javascript ...

Here, we provided afromIndexof 1, which means the search for the "JavaScript" element will start at the second element of theprogrammingLanguagesarray. Since "JavaScript" is the first element, the method returnsfalse. FAQ Q: Can I use the includes() method with case-insensitive strings?
results always the same result as - (a.toLowerCase() == b.toLowerCase()) in JavaScript? a and b are both non-null Unicode strings. If not, what would be the best collation (or solution) to make case-insensitive comparison to work the same on MySQL and JS?
match(regex); // case-insensitive match console.log(matches); // expected output: ["Gogo", "go", index: 8, ...]Note: If the string matches the pattern, the match() method returns an array containing the entire matched string as the first element, followed by any results captured in...
