{{alias}}( val, searchValue[, position] ) Tests if an array-like value contains a search value. When `val` is a string, the function checks whether the characters of the search string are found in the input string. The search is case-sensitive. When `val` is an array-like object, the function checks whether the input array contains an element strictly equal to the specified search value. For strings, this function is modeled after `String.prototype.includes`, part of the ECMAScript 6 specification. This function is different from a call to `String.prototype.includes.call` insofar as type-checking is performed for all arguments. The function does not distinguish between positive and negative zero. If `position < 0`, the search is performed for the entire input array or string. Parameters ---------- val: ArrayLike Input value. searchValue: any Value to search for. position: integer (optional) Position at which to start searching for `searchValue`. Default: `0`. Returns ------- bool: boolean Boolean indicating if an input value contains another value. Examples -------- > var bool = {{alias}}( 'Hello World', 'World' ) true > bool = {{alias}}( 'Hello World', 'world' ) false > bool = {{alias}}( [ 1, 2, 3, 4 ], 2 ) true > bool = {{alias}}( [ NaN, 2, 3, 4 ], NaN ) true // Supply a position: > bool = {{alias}}( 'Hello World', 'Hello', 6 ) false > bool = {{alias}}( [ true, NaN, false ], true, 1 ) false See Also --------
