JavaScript array methods 🚀🔥 1. Adding & Removing Elements push(item) → Adds an item at the end of the array. pop() → Removes the last item from the array. unshift(item) → Adds an item at the beginning of the array. shift() → Removes the first item from the array. ----------------------------------------------------- 2. Searching in an Array indexOf(item) → Returns the index of the first occurrence of an item (or -1 if not found). lastIndexOf(item) → Returns the index of the last occurrence of an item. includes(item) → Returns true if the item exists in the array, otherwise false. find(callback) → Returns the first matching element based on a condition. findIndex(callback) → Returns the index of the first matching element based on a condition. ----------------------------------------------------- 3. Modifying or Transforming Arrays map(callback) → Creates a new array by modifying each item. filter(callback) → Creates a new array with only the items that match a condition. reduce(callback, initialValue) → Reduces the array to a single value (e.g., sum of all numbers). forEach(callback) → Runs a function for each item (but doesn’t create a new array). some(callback) → Returns true if at least one item matches a condition. every(callback) → Returns true if all items match a condition. ----------------------------------------------------- 4. Sorting & Reversing sort(compareFunction) → Sorts the array (default is ascending, but can be customized). reverse() → Reverses the order of the elements in the array. ----------------------------------------------------- 5. Extracting & Combining Arrays slice(start, end) → Extracts a portion of an array (without modifying the original). splice(start, deleteCount, item1, item2, …) → Changes the array by adding/removing elements. concat(array2, array3, …) → Joins two or more arrays into a new array. flat(depth) → Flattens nested arrays into a single array (default depth is 1). join(separator) → Converts an array to a string, with elements separated by a given character. ----------------------------------------------------- 6. Converting & Checking Arrays toString() → Converts an array to a string. Array.isArray(value) → Checks if a value is an array (true or false). #JavaScript #JSDeveloper #LearnJavaScript #JavaScriptTutorial #Coding #JavaScriptArrays #ArrayMethods #JSArrayTips #CodingWithJS #JavaScriptTricks #WebDevelopment #coder #CodeNewbie #FrontendDeveloper #coding #ProgrammingTips #100DaysOfCode #react
